Bests & Worsts Reviews from Amazon

Worked well over the winter with daily use averaging about 12 hrs. Heat is heat. Watts in determines btu's out. There is no such thing as a magically more efficient heater (such as Amish heater advertised). Why pay more than for this one that converts electricity to heat like all the others, by heating a coil. If it lasts that is . One full winter is not a pretty good test.
