Considering the price is a 10th of what would pay for an Espar Airtronic I was thinking maybe it would be lacking in quality but I found the complete opposite as everything was packed super super nice and all the parts were put into quality bags separating them from the rest of the unit in the shipping box. I have not installed the unit yet but I can already tell the exhuast pipe isn't going to be long enough for the location I'm mounting it at to reach the outside of my van. besides that I have yet to test the functionallity but I will come edit my review when I do and add some more info.
