An interesting movie showing how the masterpiece of Sport System’s basketball backstop works: the procedure to open the basketball unit Easyplay Training, operating with a patented counterbalanced system (the same solution applied on the bigger Easyplay Official), to play position by means of just one user. The same procedure allows to block unit both at minibasket or basket heights (cm 260 and cm 305) without any additional adjustments. Flashplayer needed
