I have used the Pro Hand Heavy and the Original Gripmaster Medium over the past month to strengthen my fingers for guitar and have had amazing results. With simple exercises and such a small size, I use it when I drive, when watching TV, walking to to the mail box, or when ever it's in my hand basically. After the first week I noticed a dramatic increase in speed and endurance and recommend to anyone looking for stronger hands!
