Like anything Park Tool labeled, this tool is overpriced. Think you could use pliers as a last resort. But it matters if you go tubeless or use Continental tubes (what's the point of having removable valve cores for the tube anyway, I don't get it, you're not going to put sealant in the tube anyway). This tool makes valve core removal and tightening easy, but is small and often lost in crowded tool boxes. I wish it had a place to attach to my keychain.
