Overall this product does exactly what I needed it to do. My office building gets pretty cold in the winter and this heater works great to keep me warm. I like to just keep it under my desk and let it blow on my feet. It does a great job warming me up and keeping me warm throughout the day. Performance Overall this product works good for me. I keep is pretty close to my feet under my desk and it does great and keeping me warm. I am not sure how far the heat would actually reach but for me it does not matter. Ease of Use This product is so easy to use and is really perfect for any small area you are trying to heat up. I love using it at work! Durability I have had mine for a while now and it works great to heat up my feet and small office during the winter. Design Overall it is not the prettiest, sleekest deisgn but who cares? For me I just keep it tucked under my desk so noone can see it. Safety This product is great. In the past i have had issues with heaters smelling like smoke. This one does not!
