Review on Stan's NoTubes Core Remover Tool - Perfect for Presta and Schrader Valve Maintenance by Amrozi Goodall

I bought this simple and well designed tool to keep valve cores from coming loose when using my bike pump tube chuck. I use a Lezyne bike floor pump and a frame pump and they both work by threading the pump hose cartridge onto a threaded Presta valve. Unfortunately, if the valve core is not tightened enough, it can come loose when the pump cartridge is unscrewed. This tool gently tightens the valve cores to keep them from coming loose with the pump cartridge. Only an additional 1/2 turn of the valve core is required before the starter tube is installed. I also stowed away all my spare parts so they are ready to go when needed.
