We purchased 2 of the heaters for our basement area which never seemed to warm up.  It worked so well we ordered another one for the bedroom in the basement too!  Really did the job.  We were so surprised at the performance.  Would highly recommend!  The price and the free shipping was a great plus too.  Love how they are off the ground.  My family who came at Christmas were amazed at the difference.  And we are having one of the coldest winters in a long time but they really are keeping it comfortable.  The electric bill went up about 100.00 but to keep everyone warm and happy was really worth the cost.  Don't forget we run them 247 now so the  cost seems reasonable.
