I've had my Windmill units for a few months, and they've truly been incredible. Beyond being high-performing and aesthetically beautiful to look at, Windmill's Customer Service is unparalleled - and the Bluetooth feature is a game-changer (i.e., after a recent vacation, I was able to turn my units on from the airport via my phone to ensure that my apartment would be cool upon my arrival). I see myself enjoying these units for years to come and have told everyone I know about how excellent they are. Thank you!
