Logitech M570 Wireless Trackball Mouse – Ergonomic Design with Sculpted Right-Hand Shape, Compatible with Apple Mac / Microsoft, USB Unifying Receiver, Dark Gray

I bought one of these back in 2007, and put in a AA. I had no idea at the time that I had just purchased something that would be with me for a LONG time. To be honest, I've got ADHD and ASD, and the shiny blue, perfectly round heavy ball looked amazing to play with, and super tempting. I told myself I would NOT play with this fancy toy until the mouse broke. This would be a very long exercise in keeping my word to myself and resisting temptation. This mouse was super easy to use, I just plugged in the little dongle, and it was ready to go. Loved how quick it was to plug and play, and while the tracker ball took a little getting used to, considering I had only used the movable kind of mouse before, I found it fairly intuitive and easily adapted to using it. This mouse has customizable buttons on it, that I was able to set things to for playing MMOs, It was quick and dependable for letting me get high scores on flash games. I am an artist, and one day my Wacom tablet broke, and I just.... used the mouse. Because of the smoothness of the tracker ball, I was able to draw with it and get the lines smooth and right where I wanted them. After a year or so, the mouse stopped working! I was confused at first, and then I remembered the battery! I pulled out the battery and swapped out for another AA, and it was right back to how it was before! Darn, no sparkly tempting blue orb for me. This mouse outlasted my computer, another computer, countless laptops, and is now on another desktop.... All easy swaps of the little dongle, and no fuss. This mouse started out being plugged into a computer with XP, then was moved to one with Vista, then Windows 7, then landed on Windows 10. I've used it for art, for regular computer things, for gaming, all sorts of things... All waiting to play with the blue orb of temptation. Every year or so I would need to replace the battery, and each time I was hopeful that the thing had FINALLY worn out... I would pull it apart, use a screwdriver to clear out pet hair, whatever fluff had gotten in the sensors, put it back together, add a fresh battery, and it was always as good as new. I can't tell you how many times it's been dropped, flat out thrown (I have three kids, who are super destructive) I've moved a couple of times, got married, had kids my life is COMPLETELY DIFFERENT than when I bought this thing. At one point a hot glue gun had been set on it before it was cool, and it had MELTED a hole through the plastic... but everything still worked 100% fine. I've pretty much given up on this thing EVER giving out on me. I figure it will outlive me at this point. Aliens in 10,000 years will excavate the earth, find this stupid mouse, with its a shiny blue orb of temptation, plug in the dongle (that magically will fit their systems), and start using the mouse to navigate their space ship. So this fall, when the mouse stops working, I'm like "When was the last time I changed the battery? I don't remember. Guess it's time to do that again (I've said a year, but in truth it depends, and I've gotten anywhere from 10 months to 18 months on a battery). I pull it apart, unscrew the case, clean all the components and sensors, put it back together, put a fresh battery in, and... IT DOESN'T WORK. I'm shocked at first. I assume there's something wrong with the battery. I try a new fresh battery, and it STILL doesn't work. At this point, I check to make sure I didn't mess something up putting it back together because I don't believe it's given out. It's been THIRTEEN YEARS with this thing not having issues... THIRTEEN YEARS!!! Literally teared up and felt bad throwing this away (minus the shiny orb of temptation of course). I pop on Amazon and order a new one, the exact same thing. So far this one is exactly as good and easy to use as the old one, and I figure in 13 years or so I'll probably order a third.

I Love it: I've had this very comfortable, smooth trackball since 2011 as a gift from my family and up until mid-2015 I changed the battery 3x!. I usually use a pencil with an eraser to take out the sphere roller from the bottom hole, so I can clean it (maybe at least 3x in a quarter to remove the dust/dirt build that is seen on the sensors near where the sphere aligns. Also in that mid 2015 time period, the left button clicking mechanism was not responding very well. As noted based I on the time line I gave, I was already out of the three-year warranty and after reading all the great reviews for troubleshooting. Unfortunately, I was not able to resolve this problem and therefore opted to purchase another. Using this device I feel relieves the wrist and hand pain I had when I used the standard mouse. One will be using the thumb constantly with this unit, and it feels so smooth, light to the touch. It stays in one place and for the work that I do that consistency is a must. Do I wish it was bigger? sure but It fits well enough for my hand, I really have no complaints about that. Logitech continues to support this fantastic unit and so I feel it is well supported. Be mindful not to loose the tiny Unifying Receiver as it can take about $10 out of your wallet if it does get lost (I’m talking to those that travel with the trackball since one would have to be disciplined and remember to put it in the secure slot near the battery, as those that leave it at home will likely leave it permanently placed) . Below defines my opinionated star ratings: One (1) star = the product grossly under delivers to the point the it was a waste of time/energy and/or this was the lowest rating allowed. Two (2) stars = the product poorly represented what is was designed for even though it works (i.e. quality, stability, below par when comparing to competition). (and the manufacturer should go back to the drawing board). Three (3) stars = the product worked (in the middle), but never met my standards overall, but the functionality was simply okay. Four (4) stars = the product is good and will satisfy most that use it, regardless if there is that one nagging thing prevented it from being the best Five (5) stars = the product is the all-star/gold medal/excellent category and ether surprised me that it worked so well or it did exactly what was promised by the manufacturer.

I have 5 of these mice. Am I crazy? Yes, but not because I have 5 of these mice. I am a professional software developer; I'm on the computer all the time. Using a normal mouse hurts. Using these thumb trackballs does not, and they work really, really well. They are comfortable, on a AA battery they last for approximately 3-6 months. I don't even think about the battery. The transceiver is extremely small and unnoticeable if left plugged in. I have played thousands of hours of Steam and Origin games (Battlefield, Borderlands, Terraria, etc.) and have used only these mice to do it. I'm not too bad at FPS (I have something like a 1.5:1 kill-to-death ratio), and these mice give me no trouble. I'm not an insane gamer, so I guess I don't care about having 16 million DPI of mouse resolution. Seems like overkill to me but hey, maybe I'm a noob. The back and forward buttons are a nice plus. The ability to power off the mouse with a physical sliding switch is not to be overstated. I like having control over the battery that way. When I pack up the mouse or leave for long periods of time (if I'm gone for days-weeks) I switch it off to conserve battery. The deep sleep mode probably lasts for months regardless, but I switch it off anyway. Since it's a big ball, you'll have to clean the dirt from the little low friction rider balls (inside the "eye socket"; yes I know that's gross, but you'll be ok). I just use a plastic tool or twistie tie to clean the gunk out of there about once or twice a month and it keeps gliding smoothly. Since the rider balls are plastic, they won't scratch the mouse ball. I've had that problem with much older mice (Microsoft Trackball Optical) that used regular metal balls (the metal balls actually cracked eventually and started to score the mouse ball, making it unusable). I have had two major problems with these mice, and they only occur on my first purchase (probably made 3-5 years ago). 1. The left mouse button has started to double-click unexpectedly when pressed. Sometimes the button remains pressed although the detent has released, other times it just clicks many times. Since I have played hundreds of hours of FPS games with that mouse, it's no surprise. I replaced the faulty microswitch with one from an old optical mouse and it kept it alive for a while. Since the mouse has been used for probably millions of clicks and thousands of hours, this is really not a problem. 2. With the first version of this mouse (old one as mentioned in #1), I have experienced random permanent disconnection of the mouse from the transceiver. This is very annoying and very had to recover from. Sometimes, just letting the mouse rest for an hour or two (go into sleep mode) and waking it back up will re-pair properly with the transceiver. Other times, I've had to try special button press combinations (hold middle click for 30 seconds with left-click depressed, etc.) to try to force a firmware reset. This is not documented and doesn't work consistently. Finally, other times I would just use the logitech unifying receiver software to unpair and repair the transceiver. This usually works. I have not experienced this problem on any of the newer versions of the mouse, so I think it was an early firmware bug that has been fixed. 3. The rubber feet on the bottom have a more gooey adhesive than you might expect. This leads them to eventually slide off as dirt and dust get into the grooves around the feet. Not much you can do about this. If you keep the feet when they fall off, you can remove the fabric adhesive sticker (it's basically double-sided fabric tape) and just glue the hell out of it. Just know that the screws are under there so if you want to access the circuit board to replace microswitches, it'll be difficult if you super glue it. Yes, I know I'm strange for trying to repair my mice, but I want them to last as long as possible. 5 stars! Thanks Logitech.

This is my first trackball mouse, and I really like it. I love that it just sits in one spot and I don't have to worry about it sliding around and moving on the screen. I have it hooked up to my desktop, which is hooked up to the TV about 10 feet away. The responsiveness is great, no lag. It does take a little bit to get used to the trackball, and maybe adjusting the responsiveness, but I think it's worth it. The feel is great, and I love the extra side buttons. Overall it's well designed and functions perfectly. 2016 UPDATE: I've had this mouse for over a year now, and it's still my favorite. It's become my main mouse to use with my laptop at home. In fact, I'm going back to buy a second one for my work computer. It's great that it's stationary, so it doesn't need as much room as a regular mouse. I also have less strain on my wrists, since I don't need to move it around. I don't think I've needed to change the battery yet, because I literally just realized that the light on top is a battery indicator. Every once in a while (depending on where I'm using the mouse), it will get resistant or skippy - that just means it needs to be cleaned. Pop out the ball, clean the lint off the 3 sensor points, and pop the ball back in! That always fixes any responsiveness issues I face. I will say (for when others use your computer) those who are not used to this mouse will either love it or hate it. As I stated, earlier, there's a learning curve, and people who didn't sign up for it won't like that curve. Almost everyone who uses my mouse is super annoyed by it...I think one person loved it and wants to get her own, understanding that it's great once you're used to the trackball. But everyone else is quite confused by why I would want it... So really the only negative is other people's reactions to being forced to use it with my computer. 2020 UPDATE: The original mouse I bought finally kicked the bucket mid-2019, which was about 4 years after purchase. Its responsiveness was going downhill, mainly having issues with the left click. So I replaced it with the same thing, no regrets. I have one at work, and one at home, both for laptops. I will likely be purchasing a third one this year when I buy a gaming desktop. Basically I'm just to the point where every computer I own needs this mouse. Now that I have more than one of these, there's the real potential to mix them up (also a problem with owning multiple of any Logitech mouse receivers, cause those guys look the same even if the mouses don't). What I do to avoid any issues on that front, is put a drop of nail polish on the mouse and the receiver, so they match, and I know if I have the right ones together. (Ex- Found a receiver with a drop of holo green nail polish? I know my work computer's mouse has a green drop, so I must have left it at home and need to take it back to the office. Problem solved.) As long as the polish is put somewhere you don't touch much (or at all), it'll last a long time.

tl;dr: Well worth the price. Comfortable (for most) with convenient features. A few minor adjustments could make this mouse perfect. I work at a computer desk 12 hours a day for as long as 2 weeks at a time. At the end of my rotation, my wrist used to bother me, immensely. I needed a mouse that could put my entire arm in a comfortable position and not deviate from that for as long as I needed to do my work. I found this mouse online and could not be happier since I started using it. The product arrived within half the maximum estimated shipping time, which got me already excited. Upon initial use, I found the trackball to be stiff and took multiple movements to move across a screen (compared to a normal mouse where all you need is enough room to move your arm). Maneuvering the mouse around a screen took an intentional effort with my thumb, but I turned my mouse sensitivity WAY up on my computer to alleviate part of that issue. This mouse clearly needs to be "broken in" more than what I hear of the last corded model. "Breaking in" process: What I did to combat this initial stiffness was I turned the mouse off and held the mouse between my palms. I held the mouse firmly in my left hand and rolled the trackball around my right palm while applying as much pressure as I could between my hands without slipping and throwing the mouse. As far as the movement is concerned, think of rolling balls of dough or meatballs, just with more pressure. This "breaking in" process only took a day or two and was well worth the effort, since I am now left with a comfortable, perfectly workable mouse! I kept the sensitivity up and now I can scroll across the screen with ease while still staying precise on what I am clicking! Improvements needed: I have big hands, so the bottom end (where the palm rests) is a little too small for me. To combat this, I still keep this mouse on a mouse/note pad to keep it elevated. This isn't too much of an issue, despite the irony of still needing something like a mousepad for something that doesn't need it in order to function properly. If the palm rest was slightly higher (or there was a different model for larger hands) then that would be wonderful.

Hi I had 2 logitech trackballs in the past 9 or 10 years. It seems one of the minor complaints are that the blue ball isn't as smooth as the old Red Ball. Well I still have one Red Ball from one of my old Trackballs that broke and will test it with this new version and report back. Hey the red ball might not even work but I don't see why it shouldn't work..who knows . When I take delivery I will report back with an update . :) Edit: Well my trackball arrived today. Firs off it's much smaller than the old redball version. I wanted to test the red ball in this one but it won't fit so that's out. I'm a woman so I don't have big hands but I don't have tiny hands. That being said it fits my hand perfect. If you have big hands you might not like the fit but that shouldn't stop you if you are currently using a mouse which is smaller than the trackball. Yes the new blue ball doesn't have that slick feel that the redball had but it's still slick. You can tell the difference between the 2 if you used/owned the redball version.The blue ball is much smaller than the red ball but it doesn't hurt performance. I plugged the unifyer into the usb port and windows installed the correct driver in seconds. By the way I have Windows 7 64 and I was up and running right away..so yes no problems with windows 7 /64 for those of you that might be wondering. The 2 extra buttons on the side are programmed to go back and forward which is what I already intended to use them for anyway. Someone said the location of the 2 buttons was bad but I don't see the problem .Even if your index finger (Which is used for 1 click)were to brush up against the side buttons nothing would happen becasue they are sturdy enough for side swipes to not activate causing you to go backward or forward. And of course the scroll wheel which works as intended. This is without installing the software. There's no software DVD but you can get it directly from Logitechs website if you choose. One thing I don't care for much is the blueball location which is for thumb use. I like the old version where you used your index finger.It's just easier to control with the index finger than the thumb . It's not a biggie no no and there's no problem controlling the blue ball but I rather myself using the index finger. It already comes with a battery (Only needs one) and a duracell to boot. There's 4 rubber feet on the bottom which hide the screws so I'm guessing it should be easy to clean if need to when you run out of warranty. What I'm really pissed about is the price..I ordered this 2 days ago and now the price is much cheaper. I'm going to email them to see if I can get credit...hey it's like $10 with shipping..even the shipping was more 2 days ago. Big plus no freaking long wire hanging off the side of my laptop ! Bottom line I'm happy again :) PS:This vendor doesn't respond to emails..a simple yes or no was required of them but I guess customer service doesn't mean anything to them. ---------------------------------------------------- Edit: Nov 8th 2010 This vendor never did reply to my request mentioned above. Again a simple yes or no would have suffice. ---------------------------------------------------- Edit : Nov 11th 2012. Still working and I have dropped it many times where the battery cover and battery and ball were scattered all over and the handset itself took a nice bang when dropped. Each time I thought it was the end but nope she's still chugging along. PS: Still haven't heard back from the vendor 2 years later..LOL -------------------------------------------------------------------------- Update: 8/10/13 Still working like a champ and very surprised ,considering how many times I dropped this thing on my wood floor.

I bought this to replace an aging Kensington Orbit. Before the Orbit, I had a Logitech Marble Mouse that I used quite a bit. While I liked the centered ball on both of those trackballs, I've always missed having a scroll wheel and center button on both. While both of them have "workaround" solutions, neither one felt natural or intuitive. I use normal mice on all but one of my computers. I use a trackball on my workbench where I have limited space for a keyboard and mouse. When the right click button started to get flaky on the Orbit, I searched out a new trackball, and decided to try one with a thumb ball this time in hopes of having a more natural scroll and middle click. I saw tihs M570 and really liked that it's laid out much like a "normal" mouse. I use Logitech mice on my other computers and have always like them. My only wish was for a wired version of the M570. I'm not a huge fan of wireless mice, it seems the batteries always die at the most inopportune moments... lol Anyway, with Logitech's promise of a long battery life, I decided to give it a shot and ordered one. Upon opening the box, I was pleased to find they included a Duracell battery, not some cheap no-name battery that might last a week. The battery (it uses a single AA cell) was already in place, with a little pull tab to remove. I had already gone to Logitech's site and downloaded the latest software beforehand, so I just plugged in the USB receiver and switched on the trackball. It was immediately picked up and working in Windows. (8.1) I then installed the Logitech software and configured the extra buttons (I liked the default forward and back buttons) and adjusted the sensitivity. Right away I needed to turn the movement down slower to get the same "feel" as my old trackballs. At first I found it a little tough adjusting from the centered ball to a thumb ball, but having used it for a few days now, it just feels natural. The other buttons and scroll wheel are far better than what I had with the others. Perfect! Just what I wanted. :) As for the build quality, it's as good as you would expect from Logitech. The ball is nice and smooth, with just enough friction to allow precise control, without being too "sticky" or "slick". The left and right buttons, middle click, and scroll wheel feel just like all the Logitech mice I've had other the years. The forward and back buttons give a nice solid click when pressed, and are easy to find by feel. The whole thing just fits my hand well, and is comfortable to use. There's one indicator light on top for a battery indicator. It glows green when you first start to use the trackball after it's been "asleep". I'm assuming it will turn orange or red once the battery is low. Hopefully, and based on other reviews, it will be a while before I find out, since battery life seems to be pretty good for others that have used these for a while. So my only wish would still be for a wired version, but if I do have to go wireless, the need for a single AA cell coupled with a long battery life make it easy to swallow. Honestly, if the battery life is close to a year like some others (and Logitech) claim, I kind of prefer wireless just so I dont have the wire to fight with getting in the way or when moving the trackball off the work bench. Even if battery life isn't great, it's a small price to pay for a high quality trackball that meets my needs in every other way for a great price! UPDATE on the battery life... Here we are 9 months later, and I'm STILL using the AA battery that was included in the box with this trackball... lol My concerns about battery life were not warranted. I use it every single day for a few hours, and never turn the switch off. I just let it "sleep" when not in use. Everything still works as good as new with no signs of wear yet. 100% impressed with this trackball. Buy it, you'll like it!

I've owned two of these (one old version with the WiFi dongle of doom, one wireless M570 - this model) and about to buy a third (like I'm ordering it now after I post this). Unlike the ooooold wireless models with the big Logitech dongle, the little USB key works very well. NO lag or sluggishness. Helps to keep desk below the placement of trackball clean, and then bi-monthly clean the little nylon runners (simply using paper towel works fine). However they do wear out if you use it daily nonstop with a lot of copy-drag-paste work (as I do). Just for reference the one I'm about to replace was purchased November 4, 2012 and put into use next day, and it's now April 2014 and need to replace. What wears out? The top left mouse button -- this will start to exhibit double click behavior vs single click as it begins to wear out and becomes less of a click - not sure if switch is repairable, but at this price worth it to replace. I use quality rechargeable battery (Eneloop), and lasts weeks, not days. Hey! it has an OFF button on bottom if you only use it once every couple of days. If you do a *LOT* of work for days straight (think five 10 hour days), you may still get finger and joint pain, and if this happens I switch off to using the Microsoft mini-notebook optical mouse since it doesn't need mouse pad and use an orange squeezy ball to retrain my muscle memory that my poor hand can do other things besides work! Upshot: highly recommended. I'm testing one of the Kensington scroll-ring trackballs, but still too weird for me as I'm used to the scroll wheel so much I don't think about it. (Just fyi, I am now 50-something ...) Ironically ... with a little compressed air blown at the switched, the old one from 2012 lives on. Been using it the past week since I posted review, still keeps on working under daily heavy work-load! SO, new one still in box. Will keep for when this one REALLY gives up the ghost. Not that trackballs have a ghost, but .... ;-) ========= UPDATE 4/6/2016: Note for heavy users like me; meaning 60+ hours per week; the buttons may start to wear out around 2 years. So be aware if you also kill the CTRL OPTION SHIFT CMND buttons on your fancy Cherry switch keyboards, you will run into same issue here. "Average" user might get 3-4 years out of one. I am now starting on unit #3; each has lasted exactly 2 years of HEAVY daily copy/paste use for webdev, and marketing, social, stuff. --- massive amount of daily copy/paste, drag-select-click stuff. So, if you're worried about lifespan. The rest of it is bullet proof but the buttons either side of scroll wheel will eventually tank if you use them nonstrop on daily basis for 2 years. $25 every 2 years -- I can totally deal with that. :-)

La trackball, la boule bleue, est le seul élément qui fait bouger la souris. J'avais mal compris, je pensais qu'elle était hybride et qu'on pouvait l'utiliser aussi comme une souris classique. Pour autant, j'ai adopté cette souris; au départ, j'avais un peu de mal à être efficace, je mettais globalement du temps pour tout; fermer un onglet, bouger une fenêtre, me positionner sur un champ de saisie... Après quelques jours (5 au moment où j'écris) j'ai eu aujourd'hui au bureau où je travaille avec une souris une sensation inconnue jusqu'alors : J'ai réalisé que les souris classiques étaient inconfortables. J'ai sérieusement envisagé de m'en payer une pour le travail. Je l'envisage d'ailleurs toujours. A ce prix, ça va :) Ce n'est pas rien, mais ça va, la souris est vraiment bonne. Aujourd'hui, je me dis que je pourrais à peu près détourer une forme avec cette souris - je viens d'essayer et effectivement j'arrive à beaucoup plus de précision que ce que les premières minutes d'utilisation m'ont laissé envisager. C'est un détourage crado, je ne pense pas que cette souris soit adaptée à un graphiste par exemple. (bien qu'il doit bien y avoir des fondus qui arrivent à réaliser des chef-d'oeuvre avec). Là où je vois la différence c'est le renversement total dans la vitesse de déplacement. Une fois qu'on a progressé et qu'on est un peu plus net dans les mouvements, on envoie la souris où on veut en un coup de boule (si je puis dire). Au départ je trouvais pénible de ne pouvoir sélectionner rapidement un onglet dans mon navigateur web, aujourd'hui je trouve beaucoup plus rapide et confortable de naviguer avec la trackball.

Estoy bastante satisfecho con mi compra y se la recomendaría a cualquier persona que busque una alternativa ergonómica al mouse convencional. Decidí probar este mouse debido a que estaba desarrollando cierto dolor en la muñeca debido al prolongado uso del mouse en el trabajo y al cabo de unos pocos días el dolor y las molestas habían desaparecido. La mano descansa muy cómodamente sobre el mouse, lo cual habla bien sobre su diseño ergonómico. La calidad de los botones hasta ahorita me ha parecido buena, al igual que la rueda central. La esfera es bastante suave y me parece que su tamaño es muy adecuado al tamaño del resto del dispositivo. Creo que tengo manos tamaño promedio y creo que este mouse también resultaría muy cómodo para alguien con manos muy grandes. Sin embargo, pudiera ser difícil para alguien con manos muy pequeñas el tener un manejo ágil del mouse. Después de alrededor de 6 meses de uso no he tenido que reemplazar la batería y nunca he llegado a tener ningún problema de conectividad con el receptor incluído. Sin embargo, si pudiera mejorar algo de este producto sería el agregarle la conectividad Bluetooth sin necesidad del receptor (hay un modelo más reciente de este mouse que ya cuenta con esa característica=.

Amazing Mouse. It gives you a good control of working as well as gaming. The track ball takes your experience into an old era and very smooth progressions on the screen. You don't have to drag this mouse to extreme ends to move the mouse cursor across. The Track Ball does this magic. The Mouse remains stationary and the cursor is controlled by the trackball. Everything is good about this mouse. Along with the mouse I got a Duracel AAA battery which I am using since about 3 months now, and it is still performing good. Ofcourse, I turn off the mouse power button at the bottom when I am done using it or when I am moving away from the desk for a long time. This saves a lot of battery.
