Verified Purchase(What's this?)
This review is from: Max Fitness 75cm Exercise Ball with Foot Pump (Black) (Sports)
I've been using this ball as a computer chair since it arrived a few days ago. Really feeling it from my abs down to the tips of my toes.
Two not so great things about the ball are (1) the material it's made of bonds to paint if it touches a painted surface for a few hours and (2) it is extremely difficult to remove the air plug when you need/want to adjust the air pressure. The latter especially is a design flaw I hope the company addresses.
