This is the second anti-burst ball I have purchased. My first one was supposed to be 22" diameter but was 19" when inflated. The quality was good so I decided to order a bigger ball to use as a chair and keep the smaller one for exercising. Well, this 30" ball inflates to 22". I wish I had known this before ordering. Are other purchasers getting the correct size? It is a quality ball, so I would recommend it but be aware these balls are much smaller than stated in the description. FYI: balls were inflated using an air compressor, not the hand pump that comes with the ball.

i was soo upset about my shipment it came in the box that pictures the ball all over it a week and a half before christmas so naturally when my husband got the mail he already knew one of his gifts. very upsetting. but overall the ball is good. just have it shipped somewhere else if its a gift

I have no complaints. I do suggest finding a machine to air it up with instead of the hand pump or you will be there all day.

• How accurate was the sizing? Didnt quite air up to the size on the package but very close.
• Please tell us about the quality of the product. So far so good no problems.
• Was the product free of any manufacturer defects? No defects.

This is my second gym ball. I bought this one specifically to use at my desk at work. My home ball is slightly smaller and so I bought this one because it was the biggest I could find. I really like it. The smell others have complained about sent away within hours of my airing it up. My only fuss is that I've had to add air a couple of times but I believe it's because I'm on it so much and it is stretching to it's full size.

• How accurate was the sizing? The sizing is accurate
• Please tell us about the quality of the product. Very sturdy
• Was the product free of any manufacturer defects? Yes

i can't get this ball to fully inflate anywhere near 76cm, maybe the pump is just not good. once it gets kind of full, the air starts coming back out through the pump. :(

I love it. it is the first "ball" for me to own. I used the pump to "burn caleries" and i'm fine. still here. some people either don't have the time or the patience to air up the ball. but it isn't difficult to do. I have replace the office chair with the ball and it works for me. I'm short and the ball is a great chair for just about any thing.
