wrote my first review in Jan 2008. it's already feb 2010, and i still LOVE it! -- took a while to "warm up to you" but it's great. Literally, it took a while for the heater to "warm up to you" that you could actually feel the difference, but after leaving it on for a good couple of hours, just going to the next room was a HUGE difference. The heat it generates lingers, such that even after turning it off, the heat is still good until the next day. Love it!
