User Ratings and Reviews
5 Stars Solid, durable product.
I bought this ball to use as a chair, and I’ve been very pleased with it. I’m a big guy in a house that frequently has a lot of kids, and the ball has held up extremely well to heavy usage.
5 Stars Great at home exercise.
This ball and video were a great way to get a trimming work out without having to go all the way to the gym on days with little motivation.
2 Stars Deflated before we got a chance to use it
This was a disappointing purchase because the ball deflated before we had a chance to even try it out. We don’t know how it happened but there was a small cut on the side so it’s anything but durable. When I called the Firm’s customer service to report the problem, they said they couldn’t help me, that I’d have to call Amazon because I didn’t buy the ball from them directly. All I wanted was a patch but, again, they couldn’t help me. Amazon came through as always, providing a return label and a complete refund. I would recommend buying a real physio gymnic ball as we’ve had one for eight years by SkillBuilders and it still looks like new.
1 Star Not What I Was Expecting
When I was reviewing my order online it looked great, even had a 97% rating. When I got the work out ball the pump was missing the needle and the whole on the ball to pump it up was also missing a piece. No matter what I tried there was no way I could pump up the ball, so this was just a waste of money.
5 Stars Makes a great chair
I use this as my desk chair at my computer at home. My back feels much better since I made the switch. And it is easy to take a quick stretch break while you are working.
