Review on 🚲 High-Performance Mini Bike Pump: Hopopro Portable Floor Pump for Bicycles - Hand & Foot Activated Tire Pump with Presta, Schrader, Dunlop Valve Compatibility, Including Extra Valve and Gas Needle for Road Bikes, Mountain Bikes, and Balls by Jose Ballard

Looks like a good pump. connects firmly to the valve stem and inflates the tire easily and quickly. A 9 year old child used it with the first adult instructions with no problem. Also use with an adapter to inflate a ball for a child to sit on and bounce on; worked well for this - that's a huge amount of air compared to a bike tire. The only complaint is that the instructions on the box and everything else on the box are printed exactly as a mirror image: the box needs to be held up to a mirror to easily read the print. Made (and presumably printed) in China, so it's no wonder the print is of poor quality. I am considering getting one for my own bike.
