A cornerstone to my improvement
I’ve found that when I want to learn a new lick or song my hands are already ready for it, dexterity-wise, which makes picking up new songs go much faster. I’ve been using it regularly for about four years. Unexpectedly, it greatly improved my tab reading. I usually use this as warm up to practice. I’ll do five various, two-minute exercises, it’s something I don’t have think much about and can just jump in and knock out a workout and then do whatever’s next.
