Minus 1 star because paid for 24-48hr shipping and it arrived a day late. Other than that works perfect with my parksmart unit after i figured out that this unit has an internal fuelpump so i had to remove my external fuel pump setup for it to work

Did not work
No good, bought this one to replace the factory Espar heater in my Mercedes sprinter, was not the right model for direct replacement, and this company wouldn’t let me return it unused and in original boxing..
