Title: Quiet and Efficient!
Review: I have owned earlier versions of this heater, which were taller. Although those were great products as well, there was always a small hum. The newer, shorter, and longer version seems to be putting out more heat, and is almost deadly quiet. My only criticism is that the previous version had a spot in the back that had a "hand cup" in order to grasp the unit and move it, without touching the hot surface. This version does not have any place for a "handle" or someplace to pick it up. You have to grab both ends and lift up, and be really careful not to touch the hot spots. I like the low profile of the new design. Overall, I give it 5 stars and have purchased 3 of them. Amazon shipped FAST, via free regular shipping, and I received the product within 3 business days.
