Any coach will tell you that puck control practice with a ball is the fastest way to improve your stickhandling technique, speed up your wrists and work on your nifty moves. The HockeyShot Extreme Stickhandling Ball is just a bit lighter than a hockey puck (4.1 oz. vs. 6 oz.) so it moves faster for quick back-and-forth exercises, but it's heavy enough to still give you a puck-on-the-stick sensation. The 2-inch diameter fits perfectly on the blade of your stick.
