I had bought about two of these several years ago. One lasted for only a year, the other one lasted for about 4 years. I would recommend this for the use of small rooms such bedrooms or bathrooms. I like the fact that it stops running as soon as the room hits the right temperature. Performance Performed just as I expected it to. It kept my room nice and warm since the heat didn't make it to my room with the furnace. Ease of Use Very easy to use. No one will have a problem using it. Durability One lasted years longer than the first one did, might have to take it apart and fix it. I would like to get it running again so I don't have to keep my door open every night. Design I really liked the design. There is nothing fancy about it which I feel keep the cost of these little heaters down. Safety Because my dogs like to sleep with me, sometimes they would knock it over and it would shut off right away and it is safe around small children. Having three grandkids running around, I don't have to worry that they will harm themselves with it or that it will cause a fire. I absolutely love this little heater.
