Good buy!
I think this has really good features, installation wasn’t hard at all and it’s built well. I would recommend this to anyone that needs an additional unit.

Great so far
We are using this in a small bedroom in my mother in laws home and this week in Texas it has been summer temps. She likes it and it cools the room very easily it was easy to install and she is happy having a cool room again. Would recommend this brand of ac depending on room size this is in a small bedroom.

Works really good!
This unit it great for smaller to medium size rooms. It easily cools the room without taking long to cool it. I tried the heat option as well to test it and it works really well too but feel like it takes a little longer to heat up the room. It was easy to set up and easy to figure out how to use it.

It's so great and works so amazing!
Installation was so easy, and it took less than 10 minutes! Seems to be very quiet as well. i can hardly tell it's running unless im in the same room. it's on in. It works so well and cools my entire 900 square foot house! Even on the 89-degree day we just had! I love being able to set the temp, and when it reaches it, it turns off! It's such an amazing unit!

Easy to setup.
This a/c unit was a snap to get installed. It did take two of us, just to take pressure off the window ledge.
I ended up putting it in my office about 5ft from my desk. Customers comment how quiet it is, and ask me where to get one. I love that it has a remote. My other ones have not came with one. I am thinking about getting a few more units for the office.

Works great
I received this influencer promotion to give an honest review about the product. My room has no windows, so I had to put the air conditioning on the wall. This air can be used in windows or walls. The installation was not easy, but it was achieved. This air conditioning helps a lot to cool the bedroom. Since the sun gives direct and with the HVAC, it is not enough to...
