I thought this was pretty cool. A bitt more expensive than getting "the key", but you leave them on. I think I'm buying a set to try out.
I'll pass. I have the key, and it takes about the same time to set the intonation and actually has less steps than these things. Plus, since most of my guitars have Floyds, I need one key vs one set per guitar.
I'm down to only having one guitar with a floyd, so yeah I bought a set.
They look pretty cool and work as intended:
