Title: Good Hand Exercise Unit
Review: This Gripmaster is helpful to strengthen your grip, fingers, and forearms. As a drummer and guitarist, it is crucial to have good lower-arm and hand strength, and Gripmaster definitely helps develop the strength. It also good for stress relief. I'm happy with the product to date (which has been about a month every other day).
