It provides heat, but the odor (plastics off-gassing?) has been a problem.  I had to keep it outside as much as possible to (a) have hot sun on it to help release the smell (b) breeze to help air it out.    After one year the smell has been reduced, but another (similar) heater by Safe-Heat  works well and doesn't have any odor.   On both heaters I like the 1 hour timer.
