You can’t become better in hockey if you don’t work on your weaknesses. The NetKnight ShootTutor is an app-enabled robotic hockey shooting trainer that lets you control how quickly its openings change. It forces you to keep your eyes up while shooting to hit the target.
NetKnight has a ballistic nylon shell, smartphone controlled motor, and panels that open and close. The robot opens/closes them once every 5 seconds at top speed. You can use AA batteries or a wall outlet to power the device.[where to get it]
