Review on Extra Thick Exercise Ball For Workout Fitness Balance - Gruper Yoga Ball In 45-75Cm - Anti Burst Yoga Chair For Home And Office With Hand Pump & Workout Guide Access Included by John Frazier

I use this for my online school. It is very durable and I haven't popped it yet. I have played with it in the pool and it didn't get water in it. It came with a pump, 2 plugs, and a tool to take the plug out. The only problem I have with it is the bumps on it can get uncomfortable when I sit on it all day. Also, when you get it the material is a little sticky. But, I like this product enough to keep it 5 stars. I would definitely recommend.
