I did not think I would have any need for a bluetooth enabled room air-conditioner, but I found out that I love this feature.  I have the a/c in the master bedroom and I can start it up about 30 minutes prior to going upstairs or from anywhere if I happen to be out. By the time I get home, the room feels great.  It works very quickly to decrease the room temperature, it has an easy to clean filter AND it has the handy bluetooth.  Great purchase!
