Hey, I have read a lot of poor reviews on youtube about customer service being bad, and I haven't called them so can't comment on that. I do know that mine works very well and I'm very happy with it. I'm a recent college grad living in my parents basement. The basement was always cold and the heating through the radiator was always too much, uneven, and I just didn't feel it was good for my allergies and asthma. My dad got the Eden Pure in Sep and I've been using it since then (it's been almost 5 months now) and can't complain. It heats up the entire basement and I leave it on all the time and every day- unless I'm going away for a few days. When I come back, I turn it on and it is very quick to heat the area back very quickly and very evenly. It makes no sounds and is totally safe- don't even know it's there. My basement is basically an open hall with tv area, study corner, and workout corner and then my bedroom which is separated and has a door to it. I leave the heater right by my bedroom door and so the air gets to both my room and the hall.
