Query: Burst my bubble

This product worked well fro me until it popped when I was using it. I am well within the weight limits of the ball and it burst after only a couple months. I had inflated it using the tools provided. On the plus side they did send a replacement. If you want to do this right, put the extra money down for one of the gym quality balls, this could be you by but may surprise you one of these days.
