For four months, we had no problems with the stability ball (here: red, 75 cm), but now he suddenly blurted. The ball was not over-inflated, on the contrary, I thought for a few days that I would have to inflate it again. On it while my friend sat with our baby (!), Which were torn rudely to the ground and which both had a shock. Let's hope that all come with a fright and the little (and of course the mom) bear no damages. My conclusion: a recommendation to buy!
