This is my first yoga mat and blocks so i have nothing to compare to but i'm not sure how anyone would screw these up. They're still pretty new but the mat gives me the impression that it's probably good quality and won't deteriorate prematurely. They came in one cardboard box, with the mat wrapped in plastic and both blocks wrapped together in plastic. I don't see any defects and aside from the limited color options i have nothing to complain about, so i guess it gets 5 stars.
