I bought a Storm four ball roller with three wheels about ten years ago. I used it for about three Nationals tournaments (flying in and out) and it took some damage. One zipper tab torn off and another one bent, zipper ripped loose on one end of the bottom bag, the plastic buckle connecting the top to the bottom was broken, and a plastic tab on the back of the handle rack was broken off.
I think it would have lasted a long time if I had not flown with it. Just hauling it for state tournaments I have suffered no damage. For local bowling, I just use a tote.
