This heater as much as it’s really cheep it isn’t what is described. The variable speed switch didn’t work right out of the box( I’m a mechanic of 15 years so pretty obvious how to wire it) and it’s stated that it’s quite, well it’s just not. But for 100$ it’s just that , cheep. In all aspects . I wouldn’t recommend it. I made my own mounting . The factory locations aren’t good and breakers are so painfully bad. Just spend more money and be happy with your purchase. Move past this oneSwitch provided does not work, so I will have to buy a multi-position switch now which will cost as much as the whole unit did.The heater didn’t come with instructions. It didn’t work. After letting seller know they responded was to return for your money back. That did not solve the problem plus the amount of time I wasted on getting the item, then returning it plus having to find a replacement. This company should be banned from selling on Amazon.switch was junk did not work. heater works. will see if it lasts. seemed cheap in construction but then again it was cheap in price.Ordered 2 for my utv. Switches did not work for either of them. Deffinetly a cheap product
