great fitness ball for the price. the only complaint i have is that overstock needs to have more accurate descriptions in their products. i also purchased a cheaper ball because it came with a pump, only because this ball had no info on it at all. when package arrived, it had a pump. so i spent a little extra and got a cheaper and smaller ball as well. still not disappointed with my purchases. but this isn't the only purchase from overstock with incorrect info.

I'm glad I read the reviews before purchasing this ball because the ball I was originally going to buy (based solely on its delicious purple color) was reviewed as being super smelly and THIS ball doesn't small like rubber/plastic at all. I have had it for about 2 weeks and it's working great so far. The only thing is that I kind of wish I had gotten a taller one because I am pretty tall and I wanted to use it to sit at my computer desk, so I'm a little short when I sit there. But it works well for ab workouts, etc. It was a little difficult to blow up because it takes awhile with the pump they send, and once it gets blown up to a certain level, air starts to leak out the top so you have to pump really fast. It seems a little deflated now, like it's not as full as it should be, but I wasn't able to blow it up as much as I'd like so I need to try it again. I think this problem could be solved with a bike air pump or something of that nature that I don't have.Overall, a good product, just some things to take consideration of mentioned above.

this is exactly what I wanted. The exercise ball is great for a variety of exercises.

Im not happy with the size but it does the job as they say its better then nothing

I was very pleased with this purchase. The ball inflated easily and it only took a few minutes to get it just right. I inflated it too much at first, but I would let air out a little at a time until it was perfect. I"ve been using it every day since as my regular office desk chair. I spend upwards of 8-9 hours on it each day and my back feels great! I even purchased one for my assistant and she loves it too!

Gave this to my wife as a gift. She loved it. Uses it to sit on at work and great for home workouts. The pump it comes with kind of sucks, but once inflated, it worked great.

I bought this ball to use at my desk at work in lieu of chair. I'm 5'2" and this ball is perfect size. At first the ball had a pretty strong "plastic" odor but after a few days, it was gone! The pump was easy to use and I only had to fill it once with no leaking! Definitely a great buy!

The ball is great. I ordered it to sit on at work to help my posture. I use it for an hour or so a day. It works great for when people need to sit at my desk with me because I only have one chair, so they sit on the ball.

I bought 2 of these gym balls and have been using them for almost a month now hold up very well! Pumping them up is a bit of a work out with the hand pump but seem to hold air well! Didn't have a strong oder as other have noted, happy with purchase.

I was so excited when the ball arrived but it stinks so bad and it wasn't your "new item" smell, it was this smells toxic and it's giving me a headache smell. I bought this ball because it was cheapest but definitely not worth it. Spend a little more and get a non-toxic ball!

This ball is much stronger and holds air better than another brand I purchased, but it has a pretty strong chemical odor that is disapating very slowly. Still better than one that doesn't hold air for long.

Great piece. I've had mine for a year with no problems.

It is the large size I was looking for, very sturdy and has held up for a year already and seems to have a lot of life left in it. I am 150lbs and my boyfriend is 250lbs and we both use it with no problems. It has even held up through rough horse play and 400lbs. :)

We needed an exercise ball. The 66cm was recommended. I checked several other vendors and prices were similar with cheaper ball having some drawbacks in their reviews ie. rubber plastic smells etc. We received our order quickly. The ball was as advertised , a strong ball with no unusual smells. The pump that came with it was not very useful. The ball is excellent when blown up but you do need a small compressor to blow it up. Fortunately I had one of those. All in all my wife is very satisfied with the ball and I am glad I went to Overstock for my purchase.

Great quality for the price.............................................................
