SPRI SB65VC Total Body 65cm Xercise Ball

This ball is much sturdier and more stable than other balls I have tried. I sit on my SPRI 65cm ball ALL the time when watching TV as well as to exercise. It has helped stabilize my core muscles and my leg muscles. I am 67 years old and am stronger and in better physical condition than any time in my life since my basketball years. I started using this ball in 2006 after both total hip replacements. Give one a try. It could change your life it did mine. (NOTE: I am 5''5" and 120 pounds and I prefer the 65cm ball even though SPRI recommends the 55cm ball for my size.)

This ball is a waste of money. Low grade, not very durable, the smell was terrible for weeks and when inflated it wasn''t even perfectly round.

I don''t know what else to say other than don''t buy it.

Well got this fitness ball and first impression was ho-hum, I had my doubts. Of course it was red, not blue but this mattered little to me. Paid a little more for this ball than most others and expected a little quality.

I chose this stability ball for use as an office chair based on the fact that my gym uses this brand and I was familiar with the quality. The quality of the ball was as expected but I was bothered by a few things:

1. The ball comes with a pump but it took about 20 minutes of persistent pumping in order to fill it. I''d buy a more powerful pump before I buy another ball. Breaking a sweat at the office isn''t comfortable.

2. I''m a 5''11" 145lb male so 65cm seemed like it would be a good size. However the ball was smaller than I expected it to be whether for use as an exercise ball or as an office chair. I wouldn''t say my chair or desk heights are anything out of the ordinary.

3. The picture provided on both Amazon and the SPRI website show the ball as being blue. I received a red ball and sure enough there was wording on the box that stated "Ball color may vary".
