I finally did away with my old wonky foot pump that was a pain to use, and got this instead. What a brilliant choice. There are no instructions so basically it's THAT easy to use. I inflated a few balls in a jiffy, and was eager to do more (saddo that I am). I broke the needle though so need a replacement. The foot plate is on the flimsy side and snapped in half unfortunately but I think that was due to the packaging. Aside from that, the pump does the job quickly and effortlessly, what more do you want? Thanks Amazon.
