Good air conditioner overall. The only reason why it didn't get five stars was because it take a while to start up and also to cool a room ( the room isn't very big either). I really like that you are able to download an app and use your phone to turn on and off the air conditioner. I especially like that you don't have to be connected to the same Wi-Fi in order to turn on the air conditioner (but the air conditioner does need to be connect to Wi-Fi in order for the you to be able turn it on with your phone). You can be far and turn on your air conditioner with the app! The app also let's you know how long until the filter has to be change or clean. It was a little on the expensive side but out of all the air conditioners that I have owned this falls in the top three!
