I was skeptical a product that costs 80% less than comparable German made units would be any but junk. But I took a chance and I鈥檓 glad I did. The heater and the controller have worked flawlessly since the first start up. I have the remote linked to my iPhone so I can control the heater from anywhere. I鈥檓 using a BroadLink RM4 remote linked to a Skyroam Solis wireless router. I joined the diesel heater group on Facebook and read all the posts for a month before beginning my installation. Most of the problems were related to poor installations not the unit. I chose Vevor because of their US phone number and positive comments about their customer support. I am very pleased with the product and the company. I鈥檓 mounted on the side which is OK as long as the fuel intake is above the exhaust.
