After buying several different brands without satisfaction I happened across this at a dept. store. I am 'sold' on this product. I went back and bought two more. I like the consistant heat control, the energy save button and .... my heating bill went down. I have very large rooms and needed consistant heat in one for my exotic birds and in a couple other rooms for comfort. They are low profile so they don't tip over and if they should they automatically shut off. The manufacturer spent time perfecting the space heater and this is what they came up with. Awesome and much safer than any other out there. Performance I used the heater for 5 months with positive results Ease of Use Very user friendly and the energy button is an added bonus Durability Used three units constantly for five months and all worked consistantly. Design Low profile, does not tip over easily although it does have an auto shut off if it should. Attractive looking and can easily be wiped clean with a cloth. Matte black finish is a nice finish Safety Auto shut off, energy conserve button, does not get overly hot to the touch and can be used on wood floors (at least I did) without the floor getting hot. I also used on an area rug that has a very low matt and it did not get hot.
