Rating: - good customer service, good product
I originally recieved a defective product, but the customer service perople were very helpful and immediately sent me out antother ball (before I returned the first one). The second ball inflated easily to the true size described and it is very sturdy. I am pleased with this purchase and would recommend this product.

Love it! My physical therapist had me using one while in PT, & I just bought one to continue the good work. If I have it around the house, I'm much more likely to actually do the exercises that I know I need to do, & I can do them whenever a commercial comes on during TV shows. It's sturdy, easy to inflate/deflate. I just took it on a trip out of state for aweek-long conference, & it really was easy to pack. Once @ the hotel, I asked @ the desk clerk if anywhere on site there was a bike pump, & it turned out they had a compressor that blew it up lickety-split, to just the firmness I needed. So I was able to do my exercises just as if I were @ home, & without carrying bulky or heavy exercise equipment along.

I got this workout ball because I have cats and every time I've gotten one in the past the cats seem to be able to pop them with their claws. This one is great because it can't be popped and it just feels sturdier. The only problem I have with it is that I am exactly 5'6 and it is on the small side for me. So I would recommend that if you are on the edge of what they recommend for size, go the one step bigger otherwise you will regret it.

I like my burst resistant exercise ball. I am not afraid it will deflate while I am exercising on it.
