Review on 🔌 Chamvis USB Rechargeable Electric Air Pump for Air Mattress, Boats, Pool, Exercise Ball - Portable Inflator/Deflator Pump with Nozzles - Battery Powered by Corey Nyuon

I ordered this specifically to inflate my very old exercise ball. The valve closest to this one wasn't perfect, although I got it to work. I want to reiterate that this valved thing will probably work better on NEW style practice balls. Mine is quite old, maybe that's one of the problems. The other problem, however, is that the way it's made is pretty flimsy. When a person fills the ball himself (like in my case) it's very inconvenient and a couple of times I've used it the little thing came up during the fill cycle and I had to start over. I managed to fill it properly but I think it could be of better quality. However, I've completed the task, so I'm exiting the product.
