It goes on quite easy, although i think either my truck bed is not perfectly square or the tonneau cover isnt, becuase its not a perfect fit but very very close! Either way, it goes on, it keeps everything out, and it does its job quite well.The only real drawback is those handles that are used to lock it to the truck bed. When you decide to fold it up, you unhook the handles and fold them up against the cover, they lock in place so they stay folded, but, there's nothing to prevent them from rotating. It doesnt matter if you lay these flat before folding it back, they will (or mine will) rotate out and stab the cover. I open and close mine a lot and have noticed those spots started to permanently stretch little by little, its very very insignificant right now but i worry how bad it might get in the future. I'm trying to come up with a way to prevent this but i havent thought of anything yet, its very irritating and is the only reason for not giving it 5 stars!its very aesthetically pleasing! Looks far nicer than no tonneau cover at all, and the price is great!
