Good

Tried to support USA company… function seems good, knurling is good/aggressive… however the core removers riding down the assembly line side by side, mine is pretty scratched up. Does it affect function, no however it’s nice to have too look new once. Good product, however it comes with a let down.

Didnt receive what was pictured, the one I received has the top piece being the screw on part so when trying to untighten anything, it just opens up and drops the cores inside.

Had some leaking valve cores on a central AC system and the system was already flat. Used this tool to replace all three found on my system, it has three Teflon-sealed valve cores which worked out nicely. After removal of the old and installation of the new I pulled a deep vacuum and recharged and found no leaks. Great valves, great tool!

The description of this tool does not mention that it only works on Schrader valves, not Presta valves. Its nice to have the extra valve cores, so Ill hang onto it, but if youre looking for a valve tool to help with your tubeless bike tires, better get one made for bike repair that has the Presta end that goes over the valve top. Otherwise, its a nicely crafted tool, just needs a warning about its intended use.

Well made. Ive had similar ones in the past but they eventually get misplaced so I just now got two of these. It would be nice if they had an eyelet on the cap so a lanyard could be attached and hung up in the shop. Then maybe I wouldnt loose them as often.

Excellent little tool.

Very well made and perfectly compact.
