I've been looking for a pump with a gauge on it for a long time.
With this pump, I no longer have to guess how much air is in
the ball. Now I can tell exactly how much air is in the ball
before and after I pump it up. 5 stars

When I fist got this, it seen to a good one, and the bag can be reuse and and can be zip. but the I found the out when I pump the ball, it break my needle very easil.y mainly due to the poor deisng that doesn't leave too much space between the pump and needle, which will easily breakt he needle, avoid this and get a different one,. 1 star
