Black Mountain Products Professional Grade Stability Ball 55cm Black

Love the ball it does take awhile to pump it up

Perfect! Just what I needed! Thanks so much!!!

Great deal. Liked the color. So far hold the poundage.

It was a great deal. Liked the color.

Setup was easy, the pump is pretty cheap plastic and not great to use, but you only need to use it once to fill the ball anway. Be careful not to kink or break the plastic hose connecting the pump to the ball. Ball itself is great. Make sure you use measuring tape to get the ball to the correct size. I thought it was full after pumping initially, but turns out that the ball will expand a lot to get to the final measurement.

great ball with one problem. i was pumping for a while. i started counting pumps. 65cm ball takes over 2,500 pumps.

Takes forever to blow up. First I tried electric pump I used to blow up pool floats, got it to 20" and than kept running but did not have the pressure to inflate more. Than I got my high PSI electric pump I use for car tires, that worked and blew it up to full 26" as I held a tape next to it. However the ball was rock hard and I kept falling off it... LOL I deflated it to about 24" and that works. I did not even try the little pump that comes with it. Be a lot of work to blow it up to 26 inches. Ball seems to be of good quality with thick sides.

The plug to retain the air was missing, so I cannot use the ball at all.

it wont hold air i blew it up abd nxt morning it was deflated

Really frustrated. I made sure to buy the correct size (the same size as my previous one that sprung a leak) but it is significantly smaller. I returned the first one and bought a size larger and it is STILL SMALLER than my original. My original is a different brand so I will switch back to that brand, which is Live Infinitely..
