Title: Gripmaster Light Tension 5 pounds Nice!
Review: Great for guitar players or any string instrument. It's a real work out for your fingers when you press down on each button one finger at a time. The excercise where you make a full fist pressing on all buttons, might feel light to some, the key lies in the repetitions. If you have really strong fingers you might want to get one with higher tension. I've used it for two months and my fingers hold down the strings very well, plus they don't get tired. It's great for the F Chord.
