Is that the water (not oil) version?
We bought one for a family member, who lives up North, and, they love it!!
Mine is the oil version....sustains the temp longer before it adjusts again.
I tried several various heaters but these BY FAR work the best. Next thing to wood stove heat....the heat radiats so well.
I have carpeting so I put a silver tray underneath them....picked up at a thrift store. It also radiates the heat.
