Aahh....the old chinese.....they have no qualms about copying anything..
And they are most likely correct....out of the same factory as Waeco/ARB/Ironman/etc etc
Except..warranty ?? While they all say 3 yrs or whatever......getting somewhere or someone to repair it would be my only hassle.......getting that sorted before buying ?? then I would have no problem with the ebay " cheapy "
