When this arrived two weeks ago I wasen't sure if this would do the job but it has grown on me. This heater draws 615 watts and is amazingly compact. I actually have a 1500W heater and it's just too big for desks or nightstands. This one I use it right on my bedstand (nightstand) and it has a 360 degree tilt sensor so if you tilt it more than about 20-30 degrees it will switch of the heating element. This is a must have for safety.
The heater has 2 fan speeds that also work in heating mode so you can keep it very quite while still putting out full heat and it can even rotate about 30 degrees. The heater will also work as a two speed fan.
This would be perfect for an office desk or by your bed and unlike the big 1500W heaters it's much safer to be close to. You could have it on your desk and be just 6-8 inches away with no worries about it the heat burning you. Overall it's perfect for my setup.
