Review on 🔧 Mini Bike Pump with CO2 Inflator - Dual Mode Hand Pump & CO2 Valve - Portable Tire Pump with Patented Auto-Switching Twin Head Fit Presta/Schrader - (Cartridges Not Included) by Eric Beck

First off, the build quality is amazing. Made from machined aluminum, I'm not worried about it falling apart or tearing like some of my plastic-framed shoes do. It's nice and light, and powerful for its size too. Being able to pump manually and also using CO2 was an advantage for me. I can put this little guy in my backpack with all my other bike emergency repair tools and it takes up almost no space and space. Because of its small size, hand pumping doesn't take as long as you might think. I nearly blew up a basketball trying to see how far I could inflate it by hand. It got very high in PSI where the bump or egg started to form. That thing can build up pressure! With the CO2 port connected, it can almost inflate my giant mountain bike tire with a single 16g cartridge. Then it only takes a few pumps to fill it up completely. I've had quite a few frame pumps in my time and they never last long as they're always made out of cheap Chinese plastic. However, it is pure aluminum. And I bought it on a crazy offer which makes it even cuter. Super happy and very impressed
