This is a good product for the moderate climber, to build forearm endurance. If you don't climb on a regular basis, doing reps with this little ring will strengthen your forearms and help you avoid the dreaded flash pump.
Again, this is for the moderate climber. If you're climbing 5.11 or harder, don't waste your time.
One final note: Over use may cause tendonitis.
