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.
