I have bought a few cheaper window units thinking they were all the same. When I was never able to get cool, I thought maybe it was just my house, my room, just the way things were. Needless to say, I was wrong. This air conditioner is the best, THE BEST unit I have encountered so far. It gets my room cold. COLD!!! The app is an incredible bonus. Once it really gets hot regularly, this will be invaluable to having my room cold, even before I get home. It's amazing!! Then to top it off, it looks cool too!
