Like the fact that it is portable … Like the fact that it is portable and because it has a fan, you can immediately feel results. Can't say whether it is more efficient than larger room heaters, since we primarily use it for very isolated uses and not for long periods of time.

Wouldn't be without it This is an amazingly efficient and easy -to- use machine. We have used it often and you can even switch it on and fall asleep.....it will switch itself off.!! Excellent and efficient

Easy to use and perfect for winter! This heater is a lifesaver! I work from home, and my office is in the basement. The furnace doesn't seem to keep up with the cold weather, so my feet and hands were always cold. I decided to buy this heater and it has made a huge difference! Now my feet and hands are warm, and I'm actually able to be productive in my office. This heater is also really portable, which is great if you need to move it from room to room.

Disappointed in this heater Disappointed in this heater as it doesn't heat as good as described. It only raises the temperature by about 4 or 5 degrees and takes forever to do that.

Best heater ever! I love these ceramic heaters! Jan 1 storm blew tree on power lines, knocking down poles and ripping meter and box off my house. My neighbor ran a single power cord which I ran 1 small heat core for 12 days!!! Until power restored. This single heater kept my bedroom and hall warm enough to survive this crazy time!!! I use the 3 heaters since in every room to save on electrical bill. I love that they are also a fan with a cleanable filter!!! Safety feature works great!!!
