This is really what I’m most curious about. The functionality more so than the feature. $50 is a lot of coin to drop for valves.
And to buy them and later find I’d need some kind of adapter for my pump… it’d be hard to justify it just from the potential hassle alone.
I recently had to deal with poking through a sealant clog with a paper clip in my front tire’s valve so it is still slightly appealing to say the least.
