Review: This fan is absolutely amazing and I highly recommend it. I've purchased other window fans in the past and none compare. In fact, I will likely buy a second. Here's what you'll love: THERMOSTAT: This fan has a built in, programmable thermostat which I love. It can be set as cool as 60F. This means you can leave the fan running on a cool night and it will automatically shut itself off once it reaches your selected temperature and you won't end up waking up in the middle of the night freezing cold. The current room temp is shown in red LED lights on the display. Once you press the button to select your desired room temp, it will show your selection and after a few seconds flash back to the room temp which stays on and reflects the current room temp. The lights on the display showing the temp may or may not bother you, depending on how sensitive you are to lighting in your room at night while you try to sleep. Worst case, it's an easy to fix to cover it with something and it hasn't been an issue for me and I love a dark room for sleep. FAN SPEEDS: There are three fan speeds, low, medium and high. I keep mine on high just to maximize on air flow. It's a great breeze and strong enough fan to air out a large bedroom or medium sized living space. FAN OPTIONS: There are two small fans built into this product. An interesting bonus feature on this fan is that you can choose air in, air out, or air in AND out (exchange). The options basically change the direction of the fans to both spin to blow air in, both spin to suck air out, or one fan blows air in while the second fan sucks air out (to exchange the air in the room). Personally, I prefer the air in feature, especially if you're looking to cool off a room and it's cooler outside. DESIGN: This fan fits into my windows perfectly. What I like is that it has two plastic 'flaps' on top that grip the window and hold it in securely. Other window fans I've owned didn't have this, and without the flap, makes it much easier for the fan to fall out or be bumped out of place. This fan stays securely in the window. Equally awesome is that the fan has a built in accordion style slider that easily slides out and fills the open portion of the window. It has two lock buttons that lock the slider into place as well so it doesn't end up moving while securing the fan into the window. REMOTE: This fan comes with a remote control. This is handy for when you're laying in bed and want to adjust the temp, turn off or turn on the fan. You can control everything from the remote (as you could on the fan itself). QUIET: This fan is extremely quiet. A few times during the day I caught myself walking up to the fan to see if it was on because it was so quiet. Turns out, it was running on high and just super quiet. Still great airflow even with little noise. AIR FLOW: Great air flow. Strong breeze into the room and cools off our large master bedroom significantly without issue. These are strong little fans. TIP: The fan has a standard/average length cord so make sure the window you plan to place it in has a plug near by. If not, have a short extention cord handy to ensure it reaches the outlet. I purchased this fan based on its great desertcart ratings which is also why I wanted to give back and write this lengthy detailed review. This review is my own and I didn't receive any perks or freebies for writing it. I'm extremely satisfied with this fan and will likely be buying another one for our house. You will not be disappointed with this fan. You will love it! Five stars!!

## Questions & Answers

**Q: I have had this fan for about 2 months and love it.  But it stopped working the other day, looks to be the fan's fuse.  Anyone else have this problem?**
A: "Our fan stopped working suddenly after a year and a half of solid use on most warm days/nights. We replaced the fuse with the 5 amp mini fuses linked in another help question here ( http://www.amazon.com/dp/B004TRY2HM ), and the fan runs again!"

**Q: Is it possible to mount it and leave the mesh screen in place? Or will I have to remove it to mount it on the window?**
A: The windows in my apartment did not come with screens, I bought adjustable window screens for each window. I bought this fan and placed it in the window. It did not fit securely/correctly in the window with the screen. I paid for a cheap screen and cut it to the size of the fan,then placed the fan in the window-a perfect fit (following the installing instructions). Which ever window you place the fan,the screen will also be there. Good luck

**Q: Can you mount this fan vertically instead of horizonitally?**
A: i have very nice Pella windows. this fan is so thick i returned it. i would have had to remove my screen completely, and even then it stuck out the front so much I couldn't close the blinds.

the other issue is there's no screen anywhere in the fan (i don't think any of these window fans do) so you are going to bring in every bug that gets sucked in. and if you leave it in the window off, all the bugs can climb right in You can see just from the pic how wide the slots are.

**Q: The track that the window slides into is 24" wide (1.5" deep), but measuring the window itself when closed is 23" wide. Will it fit?**
A: With the pleated section and expansion panel removed, the fan measures 24" wide. You will need to get past the 23" wide inner dimension of your window. Perhaps you can angle it in one side first then square it up, but I doubt it since your depth is so shallow. If you are desperate to get a fan to fit, you could cut away 1/2" of the main housing on each side  with a hacksaw. I hope this helps.

*by L***2 on 28 June 2015*

UPDATE May 2018: I've now had this fan for 3 and a 1/2 years and use it almost daily for 1 - 3 hours and it is still working great. I don't know what I do without it - it keeps me from having to use my A/C all the time to cool down my bedroom. Anyway, it is still working great so I still highly recommend this product. Really impressed with it. Best thing about it is how light it is - I can pick it up with one hand. UPDATE Feb 2017: I've had this for about 2 years now and I still love it and think it works great. I use this very often and have had no problems. The one thing I've noticed is that the temp gauge is not accurate to the interior of the room, but honestly it couldn't be since the gauge is part of the fan, so it is measuring right where the wind is and not the whole room. Would be a great feature for new ones to have a remote temp sensor! Anyway, for me this is not an issue since it's easy for me to look at my temp gauge and then just calculate - add 10 degrees or whatever. But I hardly ever use the temp auto off thing anyway since I just blast it for a while before bed to cool the room down and then shut it off. I use it all seasons except summer now because my place is so hot (heat is central to building) so I need to cool the room down when I get home. The fan will cool the room quickly - I can get it from 75 to 68 in about an hour usually, which is faster than my AC! Because it's so light I have also used it in the living room which is a huge open area with the dining room and kitchen and it works well in there too, even though it's a lot of space. I love this fan and would still highly recommend it. I'm buying another one for my mother today which is why I decided to come back and post an updated review. I will start with the caveat that I've only had this a very short time (a month-ish) and have only used it about 10 times so far. I will come back at the start of winter and update this review, after I've used it for a while. I know one of the complaints with the new version is that it breaks down quickly so we'll see about that. Also, I've only needed to use it for a couple of hours before I go to bed, then I turn it off, so I don't know how it is overnight. I have a ceiling fan so after this fan cools the room, I just use that overnight. So I really have a limited view for this review, but I'll tell you what I can. The pros: It's really, really light weight-wise, which I wasn't expecting. I live alone and am not strong, so this was good for me. It cooled the room very quickly and very well - down from 80 to low 70's in about an hour. I've only used the feature that blows air in with both fans. I don't really understand how blowing in on one fan right next to blowing out on another fan would make any difference - seems to me that just blowing in as much cool air from the outside as possible would work best so that's what I did. I had it on high with the temp on the lowest setting - the fans really blow hard so I liked that too. It didn't cool the room below 70 even though the temp outside was cooler than 70, but it made it totally comfortable each time I used it. I didn't find the noise a problem - sounded like my AC unit. I guess it;s not quiet but I like white noise anyway so if noise is an issue for you, you should check out the guy who posted a review with the sound clip to see if it's too much for you. I found it very easy to install (I never have the patience to look at directions and am horribly not handy nor mechanically inclined - actually I'm so mechanically challenged that I put this thing in the window upside down at first!). I just put it in the window and plugged it in, then pushed the buttons until it did what I wanted (i.e. turned it to the coldest setting 64 degrees and high fan blowing in). I like that it is shallow enough that I can put it my window with the screen still in so I dont' have to worry about bugs or birds, etc. But maybe this is true for all of them...The cons: You can't use it sideways so it will only fit in the big windows horizontally, like in the picture. Maybe this is an unfair con but I wish I could use it the other direction so I could have it in the small window now that I have my AC unit in the big window. I did try using it on a very warm (74) and sticky night and it did not do the trick. I didn't really expect it to but it didn't in case there are people looking to use this to replace an AC unit. But there are many nights I come home and my bedroom is 80 and it's nice out and I know I could just use the fan to cool it down but I can't because of the AC unit in the big window. It's not quiet but I didn't find it terribly loud, either. But as I said I like white noise so this doesn't bother me, but it might bother others. So far I love it. I think if it breaks down after not much usage then I would change my mind so I'll come back (if I remember...) and post another review after I've used it for a while.
