I wanted to use it for hoop and exercise ball. The instructions weren't clear on how to fit the valves other than the tires. It looks like you screwed them on, they have a threaded end, but they don't. You need to insert the threaded end into the tire valve and close it. It is sad that the photos of the order description are more informative than the attached instructions. I didn't look at all the pictures when ordering, they show it at the end of the tire nipple, otherwise I would have given a lower rating.
