This is one of the most poorly constructed objects I have ever purchased. It's made entirely of cheap plastic and feels like it's going to fall apart in my hands. You'll have to find someone to help you inflate things because you need at least three hands to use the pump since the hose comes apart if you don't hold it together on both ends. Imagine trying to hold the hose together in two places and pump at the same time. Add to that the additional frustration from a poor seal that allows a great deal of air to escape as you pump. I can't claim that the pump doesn't work since I was able to inflate my exercise ball. So if none of what I'm complaining about bothers you, the pump does inflate things and is rather inexpensive. But if you want a quality pump that is easy to use look elsewhere.
