I bought this to continue physical therapy for my elbow/forearm, as I thought it was similar to the ball I used at PT, but it's not. The ball I used at PT was uniform density and balanced - it was only 1 lb, but the entire ball was uniform and I was able to rapidly bounce it against the wall and also perform an exercise where I drop the ball about an inch then rapidly snatch it back up, and repeat. [extend arm straight out with ball in hand and palm facing down. Release the ball, then quickly grab the ball while keeping hand orientation the same. repeat until forearm muscles burn]This product however is not uniform density. It feels like there is just a bag of sand inside the ball, so the weight is correct, but the balance is not there. When I try to perform my exercise of dropping/catching rapidly the sand makes it feel unbalanced because it is sloshing around inside the ball. Similarly the ball does not bounce against the wall because the sand just sloshes around as you do it.Besides that issue there is nothing wrong with the ball. This issue is a deal breaker for me though, because I'm unable to use it for the only thing I need it for. I read reviews before purchasing, and although it was mentioned it was filled with sand, I did not realize how much of a balancing issue that would create for my personal situation.

Will work well for my exercise needs but bigger in circumference than I expected

I really need to start looking at dimensions, thought this ball would be a lot bigger... so cute though. Gave me a good laugh...

These weights are very poor quality and the seller doesn't stand behind the product. They have a weird crunchy feel to them and are not like what I had been using at my gym. The quality is very poor. DO NOT BUY these. It seems they cannot be returned. A total waste of money.

The sand moves around so the weight can be hard to control

Meets my needs and a good size to work with.

good choice to work your fingers and wrist.

good. A salesman recommended it, though. I never really wanted it.
