Top critical review
it is good quality and strong
on 7 March 2016
Did not fit the silver, 75cm Reebok gym ball. It protruded too far and did not seal the hole. Did not fit the 55cm purple Boots gym ball for the same reason. Not point complaining or returning - postage would have been more expensive than the item.
PLUS SIDE, it is good quality and strong, so if it fit the ball YOU have, then it is fine
