Big fan. I did a lot of research before ordering a portable AC unit - and I’m so glad this one stayed true to its reviews! We have an awkwardly tall window, 56 inches, and this was one of the few which fit that size of window. Beyond the fit, this thing is a BEAST! We used it for a spare bedroom where the AC doesn’t do its best. This thing kept the room cold and comfortable for 5 days in a row. NO LEAKAGE!!!!!!! It is relatively quiet. Easy to set up. Easy to use and understand. My favorite setting is that you can turn the display off at night so there’s no light coming from it. I highly recommend!

The media could not be loaded. works awesome. build quality is great, and it's very easy to use with a nice remote control, and customer support(if needed) is very responsive. the cooling ability is great on this unit. it cooled the big room from 79-73 in about 20 min. the size isn't super big but also not that small. about the size of a mini fridge if that. the fans are very quiet as we are used to sleeping with a box fan on. the 100* days that we have it kept the room right around 71 witch is where i set it to

Keeps my area cool. Almost too cold at times. This was easy to set up. It’s quite compared to the last one we had. This has easy installation and I like the window kit.

My old house doesn't have central air so I've always used a portable room AC unit. This is the 2nd one I've purchased and I can't believe how quiet it is! The floor fan is louder than the air conditioner. My old unit was so loud that I'd have to crank the volume on the TV up to 35 when it was on. I'm so impressed so far. It seems easy to operate, it cooled the room down quickly and it's attractive. If my opinion changes I'll provide an update. UPDATE** I purchase the 1,400 btu unit for my downstairs. It claims to work in a 57 1/2" vertical window but it doesn't. My window in 57" and we had to use multiple layers of foam to fill a 3" gap. Other than that, the unit is working nicely.

Saved me this summer. Works very well, not to noisy, easy to adapt to the window opening.

I’m extremely impressed with this 12,000 BTU portable air conditioner! It cools my 500 sq. ft. space quickly and efficiently — perfect for my large bedroom and even works well in the garage. The auto-evaporation feature is a huge plus, as I don’t have to worry about constantly emptying a water tank. It runs surprisingly quietly for such a powerful unit, and the remote control makes adjusting settings super convenient. The sleek cold white design also blends in nicely with my decor. I was initially worried about the installation, but the video was extremely helpful and made the whole process much easier. Great support! Highly recommend this unit for anyone needing reliable cooling in a larger room or workspace!

Updat after 3 months: quit working correctly. It doesn't stay in the mode I put it in. Would not buy again I bought this based on reviews. Having used this for about a week I can say it's confusing and the instructions are much help. I literally never know what the hell this thing is doing or how to control its settings. I feel like it automatically changes its settings to whatever the heck it wants to do. Auto evaporation doesn't work well either. The only pro is it cools pretty well

If you run this in a room that is already cool, you'll be fine. It works great in a trailer that is about 85'. But, we needed it to keep a showroom trailer cool and it was 107'. It kept shutting off. It never did work to get the trailer down under 100'. The point of an A/C unit is to reduce the temperature. Not sure why it would shut off if it's really hot. Brand new device.
