Title: It is what it is -- cheap and functional
Review: Heats up your feet and employs basic laws of thermodynamics (heat rises) to keep the rest of you reasonably warm. It's ugly and strictly functional, but uses about 1/15 the energy of most space heaters. I use it in an unheated home office, and periodically find myself putting my hands under the desk to keep them comfortable on very cold days, but for the price -- both initial and long-term (considering energy consumption) I have absolutely no complaints. Smells like a rubber mat, which is what it is.
