Max Fitness 65cm Exercise Ball with Foot Pump (Pearl White) Decide Now

The fitness ball itself is fine - although it gradually loses air over time.

The main problem is the pump. The pump is complete crap. While pumping the hose will detach from the pump, you'll lose a bunch of air, you'll reattach the hose, and then the valve will pop off the other side causing you to lose even more air. Basically, it will take 5 times longer to pump up the ball than it should.

It's a good ball, but the pump will test your patience (and your ability to find small objects (the valve) that have shot off the pump half-way through use).Get more detail about Max Fitness 65cm Exercise Ball with Foot Pump (Pearl White).
