I have needed to pump up my exercise ball for months, and finally decided to buy one. This pump is perfect because it have several different nozzles for various needs. I pumped up my infant's inflatable tub as well. Great buy! 5 stars

I had two hand pumps and another electric but they could not provide the pressure and the firmness I wanted on the ball. This pump is great if you don't mind 1 or 2 minutes of a mini arm workout, but hey to get the pressure you would have to purchase an expensive air compressor from the auto shop. I's rather have this because its also quick to use. 5 stars

This is a no-brainer. It's not much more expensive than the other pumps, but it has done everything I've needed since I bought it. It QUICKLY inflates and deflates a variety of items from pools to beds to exercise balls and inflatable toys. 5 stars

I inflated an exercise ball in about 90 seconds, as compared to the little toy pump that the ball comes with, that takes like all day. This pump is designed so that each stroke - BOTH the up strokes and the down strokes - work to inflate the object. It was powerful and easy to use. I was very impressed! 5 stars

I got an excercise ball for Christmas which did not come with a pump. I bought a pump at a well-known store which shall remain nameless. Although it was a two-way pump, my daughter pumped for an hour and I pumped for an hour and the ball still had wrinkles. "That's it", I said and just clicked on Amazon. The vendors were very effient and a few days later the pump arrived.

Half a minute later, the ball was pumped to the max. I was amazed. What more could you ask for. It works. 5 stars
