Sorry if this isnt the right section i wasnt sure but does anyone know if fingerweights are any good? will they actually help my playing or just be a waste of money?

Thank you for your help
*bump* I'm also wondering. I'm not up to the speed I'd like to be, because I'm mostly playing folk as the staple of my songwriting. But, I want to keep my chops up (so to speak) for anything heavy, so anything to help boost that small margin of my practice time would help.

Anybody know?
