Thank you for the warning and hope you heal quickly!
Just a couple of months ago, I used my very old (10+ years and I don't know if it was even anti burst) stability ball for a Cathe workout and decided right then and there I was going to replace it because it was an accident waiting to happen, and ordered a new extra thick/heavy and anti-burst one on amazon the same day. I feel much safer now. Still, I didn't think about how it could burst at the seam!
