This weighted puck is an excellent tool for developing shooting and puck handling skill in players at the bantam level on up. For younger players it is probably too heavy for them to gain from working with it. But for players who have reached the age where their natural strength is starting to develop, at 10 ounces versus 6 ounces for a regulation puck, it offers enough challenge in stick handling and shooting practice without being so heavy that it causes the player to abandon proper form. Stick handling with the heavier puck increases forearm strength resulting in better puck movement. For developing a powerful wrist shot or backhand this is definitely the right tool. Also, it can take a beating against the boards and is no more damaged than a regular puck. Of course it cannot be used to practice slap shots for the obvious reason that sticks are not designed to handle the weight without damaging them.
