It smells like melting plastic when you run it for very long even on low heat. It defeats the purpose of using a space heater to warm a room because you are afraid something might catch on fire.  We used multiple times thinking it might get better but it still smells after a month. Also the remote is very touchy and has to be pointed just so or it won't work, so don't buy this one for the convenience of turning it on or off from across the room
