For the most part, its working fine in the month since I've bought it.  Two things I wish were better: 1. I keep it in Cool mode but it constantly switches over to Eco mode on its own.  This means that in Eco mode, it cycles on and off and this wakes me up at night.
2. I just wish I could set the temperature lower than 65.  I sleep warm and would much prefer to keep the room at 63.
