Using your SKLZ Professional Indoor Mini Basketball Hoop Set is a piece of cake. First, take the foam - padded slide - on door mounts and attach them to a suitable door. Then, assemble the hoop and the backboard according to the included instructions. Once assembled, mount the set on the door using the mounts. When you're ready to play, grab the 13cm Pro Mini Hoop Basketball and start shooting some hoops. Remember to use proper force when doing slam dunks to avoid over - stressing the spring - action break - away rim. For maintenance, keep the hoop clean by wiping it with a dry cloth. Avoid exposing the clear polycarbonate backboard to sharp objects to prevent scratches. If you're not using the set for a long time, disassemble it and store it in a dry place.
