Just what I needed.. Stopped using the pliers to unscrew stuck valve core

Useless

Works great!

Another excellent Park Tool! Works perfectly, and well made.

Not the most important of gizmos to have in your bike tool collection, but a useful device nonetheless. I use Lezyne pumps with their screw on fitting for Presta and Schrader valves as I tended to destroy presta valves with my old Zefal (SKS) Husky and HP frame pumps. The trade off is that with the Lezyne screw on fitting, Presta valves can end up backing out of the stem when unscrewing the pump fitting. Bit amusing to see the valve assembly shoot out of the fitting, but not of benefit when in a rush. I know I can and have used needle nose pliers for tightening the valve assembly, but love my tools and knew the pliers would cause damage, so I figured why not order this not so expensive Park tool. Plus it is rather pretty. It works as it is supposed to on removable Presta fittings. Have not had need for the Schrader fitting, so I cannot offer feedback on the reverse end, nor the threaded notch in the middle (to chase, or cleanup, the threads on the stem). It makes for easy tightening, and no more flying valves. Not all Presta tubes have removable valves from what I read on Gores interwebs. Schwalbe tubes appear to have them and they are what I use. Recommended.

Needed this tool for my presta valves. Works well and shipping was fast.

As usual a good product from Park Tool!

Works great, nothing work with the item or marketing of the item.

Works as expected and a good price.

Works Great, nice addition to your tool kit.
