Rating: - Easy to use FAST pump
This pump is well worth the inexpensive cost. Not only can you air up your exercise ball (those foot pumps they come with take forever!!), you can also use it for your bicycle. It's fast, easy, takes up little space. I'm really glad I got it.

This pump is a tremendous asset. I use it to blow up exercise balls and it's the best thing out there and well worth the price. If an exercise ball is just a little soft and needs a little air, this will do it in seconds.

A friend of mine introduced me to exercise balls. I watched her spend over half an hour inflating a ball that she bought for her son. She was so frustrated at the end of that time and said it was very hard. She joked that she got more exercise filling the ball then her son would get using it.

So, when I was ready to buy a ball, I decided to get something to inflate it other then a little pump that comes with some of the balls.

I love this inflator. It took me at most 15 minutes to inflate my 55 inch ball and it only took that long as I had no helper and had to put the stopper in the ball to measure then take it back out to add more air twice.

The air goes in when you pull the handle up as well as when you push it down. It takes a little strength and more so when pushing it down. I am a weak person and leaned down on it with my elbow toward the end. The average person would have no difficulty with it.

This air pump is really cool! It inflates your object when you push down and also when you're pulling the handle back up. It also deflates it too. You can also use different heads on the nozzle for different holes. Really useful pump!

I used this to blow up balloons and the different nozzles came in handy. Though the balloons blew up efficiently, I had calluses within 10 minutes. Also, the pump made squeaking noises from time to time. It would be better to spend the money and get an electrical pump.
