Product review (4 stars): works fine now. A couple times the buttons did not ...
Works well now. Flaps right above vent are made of cheap plastic and generally pointless. They were stuck closed when installed. I removed them and threw them away (probably some retarded Govt regulation made them necesary); works fine now. A couple times the buttons did not work. I was planning on returning it, thinking it was a short (probably user error) and the company called to smooth out the problem. Seems to be working ok now. The company cares; I can say that. Probably didn't want it back Im guessing, but they were willing to try and I give them credit for.
