I bought the happy buy heater in sept. The heater worked great but would shut down after 5-10 minutes. I got ahold of the seller and I can honestly say they got my probelm solved quick. They responded within 12 hours and were Very helpful, very kind and they were very fair with me. They heater is great, but the customer service is what amazed me. That is hard to come by now days. If your looking for a heater and worried about it. These guys will sell you a good heater and will also take care of you if you have questions and problems. Thanks again Emmy and Larariane!
