This space heater is excellent! It heats up my kitchen and living room. The space heater makes no noise and is very lightweight. You can wheel it room to room and it goes over carpet with no problem. It comes put together. The only thing you have to do is put the wheels on. No tools required! It also comes with a remote, which is awesome! I don't have to get out of bed anymore to turn the heat on! I'm very happy with this heater!
