Gauging one's guitar progress by the number of plucks or strums performed....yeah that's going to really develop a sense of musicality.
Seems very gimmicky, just the kind of thing that new guitar players will be sucked into buying and then end up in the closet within a couple of weeks when they realize it's not doing much for them.
Kind of reminds me of that "Chord Buddy" gizmo that was on Shark Tank a few years ago (and apparently became a smash hit). Although at least I could
sort of see the benefit of that....
