Ball is very durable, easy to fill, no air leaks, very functional for different exercises, rubber is soft and great value

Quality product. The pump that comes with this exercise ball works fantastic. My adult daughter sat on it & bounced. Very strong. Totally pleased!

As well made as any large ball. Does not inflate to 65 cm, even given more than a couple weeks. But other brands inflated even smaller. Also should include an adapter to fill like other brands. But holds air well and good texture.

This ball is wonderful, handle your weight perfectly for different type of workouts. I recommend to anyone looking to buy an exercise ball.

I use this to sit on when my back gets sore from my regular chair. It is very comfortable and I like that I can move around and stretch while sitting. So far it has held its air and I haven't had any issues. It was very easy to blow up with a tiny automatic pump that we had.

Big. Thick. Was a little tiring on the arms using the cheap little pump supplied. It was easy to use/set up.
