Continuous ball launcher perfect for tennis practice. - Product Name: Tennis Partner TOSS - Function: Continuous launch of 2500 balls - Weight: 1.0kg - Ball distance: 1.5m to 2.8m - Angle adjustment: Possible - Target: For tennis practice I found this while organizing the storage room. I haven't taken it out of the box, but the box has dents and tears (as shown in the photos). I haven't taken out the contents, so I can't confirm the operation. Thank you for viewing.
