I used mine through the winter last year and it worked just like they said it would...with no problems. About a couple of months ago, I was just fiddling around while driving down the highway, and decided to turn on the unit for some bugs....it just flashed rapidly at me....and then went dark....tried it again later, and the same thing happened. I called tech support after checking the manual, and they said that most likely the heater burnt out because I didn't prime it. I primed it the first time I used it when I installed it...and then purposely primed it after it starting glitching recently....they wanted me to send it back...I may do that, just depends on if they will send a new one or not....I have no receipt because it was an ebay purchase over a year ago...so I doubt they would replace it. So....I'll be installing my other unit when I feel like working in the cold weather - and we'll see how long it works....
But, again, it works great when it's working...
