Review on 🚲 BriskMore Bike Valve Core Removal Tool Kits: Easy-to-Use Lightweight Kit with Presta & Schrader Valve Removers and Replacement Cores by Greg Roberts

It does what it is supposed to do for such a simple tool but it is not very accurate so there is a little play when the stem is pulled out. Otherwise just fine. The supplied Presta valves appear to be of good quality. As a tip, use a small amount of air tool oil or thin silicone grease in the inlet when inflating the tire and the seal will last significantly longer without the need to replace again.
