We have had this heater for several years. We mostly use it during bath time to keep the rooms warmer. It heats really quickly and efficiently. I also love the oscillating feature. Performance Is here's a great job at meeting rooms. I often turn it on about five minutes before I go into the room to ensure that the room is warm. It left on with the door open the whole house gets warmer. This tiny heater puts out a great deal of heat! Ease of Use I have to be honest after having this machine for years I still can't figure out how to use some of the buttons and functions. I know how to use the important ones and that's what counts. Durability I probably had the heater for about five years I have not had any issues with it. Design I love design of this heater. It's small enough to store and just about any area, but also looks great sitting in the corner. Safety After hearing all the horror stories about space heaters I have to admit I'm rather scared about leaving my on for an extended period of time, however there have been times that I have left it on and it was perfectly fine. It typically cuts off once it reaches a certain temperature or after a certain time period.
