    • Easy to install and cools great
Works great. I am 74 and alone and don't want to rely on someone to put window units in. I was able to install myself. It cools my main part of the house and I just purchased a smaller one for my bedroom

    • Decent with minor headaches
Amazing Ac unit it’s hard to do manually because when you press any buttons everything resets! But it does cool as you need it which is most important so we giving it 4 stars. It’s super heavy so have something to lift it on if you have a far trip to desired location.

    • Perfect game room solution!
Easy to install and perfect right out of the box! My wife and I have PC's right next to each other that generate a lot of heat! Took less than an hour to install this AC and had the room cool in 15 minutes. Highly recommend.

    • Dead After Turning On
Turned the AC unit on and literally after 10 seconds it shut off and was completely dead. Unplugged the unit and waited 30 minutes to possibly let it reset. Plugged it back in and nothing again. Complete waste of time. DO NOT ORDER this unit.

    • Glad we bought this!!
We were originally skeptical about buying this just because it didn’t have very many reviews but I am glad we decided to go ahead and get it! So far, it works amazing! We have it in our shop (about 550 sq.ft) to keep the working dogs cool when they want to come in. The only downside- which is my own fault for not reading more closely- is that the plastic piece that goes in the window is a little too long so we are going to have to cut it to fit our window. Zero complaints about it cooling though, and I love that it turns on and shuts off automatically when the room reaches your desired temp. ... show more

    • Great product. Worth every penny I spent.
I was looking for a portable ac and I came across this one and so I started reading all the reviews. I think most of the reviews were positive, it really help me with my decision. Now, let me drop my own review on this product. I've been using this thing for 4 days now, and I love everything about this product. Easy to put together, comes with everything that you need. I'm glad I bought it. I recommend this product to anyone who's looking for a portable ac. ... show more
