I absolutely LOVE the comfortable heat these heaters put out.  The simple controls are great and easy to use.  They can put out a lot of heat in a short time and then be turned down to maintain the warmth.  You can stand close to one (but not touching!), to warm your body.  Very soothing heat - it warms the surfaces in the room rather than just blow air around, which isn't warm or cost effective.  I have two of these in my downstairs area and I am super pleased with my purchase.
