A great padlock with a big flaw. Firstly when I received it I was just blown away by how massive and strong it is. Very well done. Worth buying this XL as it blocks the wheel and frame of a small trailer. Here's the downside, the castle itself is terrible. I ripped it off easily with the stuff I had, but I won't tell you what because the scammers will try to do the same. -2 stars, I hope I fix this lock issue and new buyers get a well made 5 star item. The layered size of this item will deter petty thieves.
