Great slick surface, you can use it with a regulation puck and it slides very well. Good for stick handling practice. Even though you're limited to the space on the board, I prefer it over using a stickhandling ball or Green Biscuit on pavement.
While it's good for stickhandling, it's excellent for shooting. I've improved my wristshot technique and aim, and it's durable enough to practice slapshots on as well (I'm still working on my aim with that). Another great benefit is that it protects the blade of your stick (if you're usually practicing on pavement).
