If you're serious about grippers you've probably heard of RGC ratings for grippers.
Cannon PowerWorks is an exceptional US company that rates grippers, however the cost of shipping and exchange rate fluctuations can make this service prohibitively expensive for Australians.
Artie's Grip Gym has calibrated their rating service to match the results of Cannon PowerWorks ratings.
