This is great and it cools the rooms nicely! Make sure you get the right size or it won’t cool you room correctly. I live in Hawaii and it has been amazing at dehumidifying the room and I can turn it on for about an hour and it stays dehumidified as long as the door is closed. It also works good with the app and WiFi. I do have to say that the app definitely needs some work. But it does the job of turning it on and off so that is good. 
I highly recommend this product to anyone looking for a cheap way to cool down a room! [This review was collected as part of a promotion.]
