Review: Best mouse ever. - I purchased this mouse 3 years ago. Initially I purchased it because I was working 2 remote jobs and it allowed me to maximize the space on my desk by switching between the computers I had on there. Now I use the mouse for one computer (although the switching between Bluetooth and USB capabilities still work) and it’s the best mouse I’ve ever used. The Bluetooth connection is seamless, it’s incredibly easy to use, the design of the mouse is comfortable in my hands, the grips on the sides are still in great condition and haven’t gotten gross or anything, it’s compatible with Windows and Mac computers. Best money I’ve bet spent on a piece of office equipment, it works so well it’s even kept me from buying an Apple Magic Mouse.
Review: Great Mouse for an Inexpensive Price - This is a great mouse. I have actually bought this mouse twice. The Bluetooth connectivity works perfectly with my various computers and tablets. The usb A dongle works fine too, but I prefer bluetooth. No interference issues with the bluetooth. The mouse is a little bit small, but it's still big enough for me. And I have rather large hands. The battery life is incredible and it runs off of one AA battery. I use rechargeable batteries so I don't have to buy disposable ones. It definitely lasts multiple weeks of everyday usage on one charge. It's also a very inexpensive mouse, but you get a lot for your money. The cheapest one I bought was only nine dollars. I also use it for gaming. No problem, it is sensitive enough and responsive enough. It also has 2 extra side buttons, so that you can map controls to those buttons for certain video games. Definately recommend!

## Questions & Answers

**Q: Can the side buttons be disabled? my thumbs keep hitting them by accident and then I have to start filling out forms all over again. It's a problem.**
A: You can change the primary mouse button between right and left but my dialogue box doesn't seem to allow for disabling the side buttons.

**Q: Just bought this, windows 10 is asking for a pin can't get it to connect.   what do i do?**
A: When activating the mouse utilizing the WINDOWS Bluetooth Device utility, if you wait too long, or attempt to add it too many times it will then ask for a PIN. There is no PIN. If/when that transpires you will need to repeat the following process over again.

Start by removing the mouse from the WINDOWS Bluetooth Device catalog, IF it is registered, by utilizing the WINDOWS BLUETOOTH utility. Scroll down to where the mouse is listed and remove the device from your Bluetooth device list. If it isn't registered and WINDOWS is still requesting a pin. BE CERTAIN that it hasn't erroneously registered it and then reboot your device.

The 3 position switch on the underside of the mouse is the selector for either BT or USB 2.4. Allow the mouse to be registered as a USB device first. This gives you the option of utilizing it in either BT or USB, whichever works best for your LAN environment. Insert the micro dongle into the USB port. Allow WINDOWS to recognize and activate the mouse in USB mode.

Depending on your system configuration, you may need to utilize a wired USB mouse until you get this mouse registered in WINDOWS. I always save myself the potential frustration by plugging in a wired mouse no matter what.

Once it is registered in WINDOWS as a USB peripheral, you can then utilize the Bluetooth utility in order to pair it up with WINDOWS. Open the WINDOWS Bluetooth utility program in the control Panel.  Then attempt pairing up again.

You should initiate the pair with the mouse by placing the 3 position selector switch, that is located on the underside, into the BT position and then depressing the little round button on the underside of the mouse for several seconds. You will notice that the blue light in the mouse will begin to rapidly blink, indicating that it has transitioned into pairing mode.

WINDOWS may list the mouse twice, once as BM20-3 and again as BM20-5. It is BT 5.0 device that is backward compatible. I ignore the double registration as it simply eliminates the frustration of removing it often, plus, it adds another level of functionality.

**Q: Will it pair/work with Amazon kindle fire hd 10 (bluetooth 4.2)?**
A: It should yes, but have not tested that option and have only used it with a laptop. I have used it both with and without the attachment though

**Q: Does anyone know how to contact their customer support?  I have been trying for months without any reply.**
A: no

### ⭐⭐⭐⭐ Good mouse, but there is an issue about the button behind the scroll wheel...
*by L***L on December 19, 2024*

I paid $10.98 for mine, now the price is $13.99, but there is a $2 coupon. Regardless, it's a good little mouse for around 10 bucks. It seems very much like a low end Logitech mouse. I wouldn't be surprised is they are made at the same place, with many of the same parts. It works well. But, what about the buttons? My instructions came with a sheet explaining the button functions in several languages, but not English? It's easy to figure out the BT (blue tooth), Off, 2.4G switch on the bottom. Also, easy to guess the button above it is to set up Bluetooth, hold for a few seconds. But, the button on top, behind the scroll wheel, what's it for? I kept mashing it and nothing happened! The instructions were useless. Even the internet was no help for THIS model mouse. Meanwhile, if you leave it set for awhile it goes to sleep while using it as a BT mouse for Macbook. To get it going again I would move the switch back and forth on the bottom, but that was inconvenient. Eventually, I wrote a question here at the Amazon site and got a reply from a helpful user that it was an "awake" button for using BT. Sure enough he was right. If the mouse is asleep, tap it once and a couple seconds later it's awake. BUT! The company ALSO wrote me an answer saying it's a DPI adjusters which I don't understand exactly, but in any case, repeatedly mashing the button doesn't do anything that I can tell. I think it's a "awake" button. Anyway, so far, a good little mouse. BTW you got to have your own battery, none comes with it. I am giving it 4. Probably would have been a 3, but the price is very good. Why no one else mentions the button issue makes me suspicious of the 5 star ratings. There must be real owners with the same issue as me.
