Fitterfirst Duraball Pro Exercise Ball - 55 Centimeter

Be aware that this item does not ship with an inflation adapter. When you open the package, you'll find printed material describing plugs, an adapter, and a measuring tape as being included with the ball. That is not correct. The only items included are the two plugs. You will not be able to use this out of the box unless you already have the proper adapter. If not, you'll have to buy a kit separately.

VEry heavy duty ball. I am a heavy person and this ball does not squash down under me. It takes a while to blow up, though. Because it is so thickly walled, you won't be able to use the ball for about three days after you receive it. You have to blow it up little by little and let it rest and stretch out, then blow it up some more. Even so, I wasn't able to get it to its full diameter: it is still about 1" smaller than it's supposed to be. If I were to buy it again, I might buy the next size up.

This Australian made brand is the gold standard in fitness balls. I have an 85cm ball for years that still is good as new. I can't see trying to save a few dollars by purchasing a lesser brand--if the ball bursts while you're on it lifting weights, the savings won't seem like such a bargain.

Pumping up an exercise ball FREQUENTLY is not to my liking. The DuraBall has maintained its original level of inflationregardless of frequency of use. Pump it and forget it (the pump that is)

I have used several brands of stability balls and none have met the quality of this ball. It is nice and firm-doesn't squish down like a balloon as many I have tried have done.

Nothing wrong with it. It's bouncy.
