For the price i paid, i won't complain too much. The particular box i recieved was a bit mangled, the product seemed to be fine, minus the LCD display. It was NOT new. The screen was scratched to hell, and both remote and screen had the protective plastic missing, minus areas where it was pinched in the seams. The overall product works great. However, the fan was shifted into the body of the heater internally, and was not able to rotate, but, sometimes I pretend I'm smart, and figured out the issue. I suspect becUse of the price i paid, it was a return.Once all the minor issues were fixed, and only 1 I contacted the seller about, it is freaking awesome. I bought for my 72 VW Beetle Baja, that has no way to heat the cab, now, it's toasty, and i can warm up the car before i even go outside to start it. Fuel consumption is low, i didn't do any actual testing, but, going off the specs, 3 liters of fuel should last about 24 hours.
