Review on Origin8 Presta Valve Core Remover by Marc Cahoon

Anyone who gets stuck somewhere because they couldn't tighten the removable valve insert firmly enough to inflate the tube knows how life-saving this tool is. Sure, you might think of taking any store-bought inner tube out of the box at home and tightening the valve core with a wrench or pliers, but really, you're going somewhere with a flat tire and a loose valve core. This tool is small enough to hide in whatever you take with you (e.g. a patch kit) without causing you any inconvenience. And of course it works great because seriously, it's not rocket science.
