Balls warped when pumped up. I did not overinflate. Balls were not well laminated. The bladder protruded through the outer covering.

Flimsy ball. I bought it for a dog toy and it lasted about 10 minutes. Granted, that's not it's purpose but it won't last very long used as a small basketball, either. OTOH, it's cheap.Edit - I just noticed it's called an "enduro" ball. That's downright misleading - so, instead of two stars it gets one.

Our high school P.E. dept. gets these from our district warehouse. Last year we purchased 20 through the district. They arrive deflated in a bag. Virtually every single one developed cracks along the fold lines and within a month of inflating and using, would have the butyl liner bulging through, sometimes along multiple fold lines. On half the balls the pebbled finsih would still be in good shape and the cover would be splitting and the butyl showing through. It might just be their folding and packinging for shipping that's causing this but the bottom line is that they would pop or be unusable within a semester. Performance and grip wise they were fine before they would start splitting, good bounce and feel for an outdoor ball. You decide
