Heat Pal located at heatpal.com is noisy and useless. It's like a hairdryer, you only feel some heat if you place it very close to you. I had to pay in cash directly to the delivery man, there was no receipt or anything like that. When I realized I had been cheated, I sent a request to the company asking to return the heater and to have my money back. I got no answer from them. Don't buy it!
