I bought this item to use as a chair replacement, which means it likely gets used more often than if for exercise. I bought this items a month ago and have used it almost daily since. To date I have not had to reinflate the ball and it has been sturdy and comfortable. The enclosed pump didn't inspire a lot of confidence but actually worked just fine, and given the fact that it may not require a lot of use, should be suitable for the life of the ball. 5 stars

I had a shipping problem with my ball, and I also ended up with the wrong size. Max Fitness went the extra mile and met all of my needs with 100% integrity. They were pro-active and gracious.

I also love the ball. One qualification for those of you considering getting a ball. The size of the ball may depend on not only your height but what you are using it for. In my case, I'm 6' tall and I use the ball to do Core Exercises as taught by Gunnar Peterson and the 65 cm ball is definately too small for me. The 75 cm ball works for me, and I'm completely satisfied both with it's quality and the excellent service I received from Max Fitness in the process.

You can't go wrong with these folks. 5 stars

just as described, works great, bigger than it looks at first. plastic smell goes away after you leave it in the shower under hot water for 10-15 minutes 5 stars

the ball was very useful in my home training and gave good support to my lower back for all exercises. i like the ball training method too. 5 stars

I like this ball now that I have it set up- it's great for stretching and even as a chair. However, when it arrived it had an oily residue all over it accompanied by a terrible chemical smell- maybe I'm just oversensitive to these things, but it was really overpowering. I washed it as best I could, and the smell has faded over time, but avoid this product if you have any sensitivity to smells or chemical.s 3 stars
