Thank you for viewing. This is a toss machine that supports both soft and hard baseballs, with adjustable launch distance and angle. It operates on AC power and dry cell batteries. * Uses 8 D-cell batteries. I used it with AC power. * I think it would be good for those who have a portable power supply for outdoor use, allowing for light practice before a game on the field. I purchased it for personal use in my yard, but I didn't use it as much as I thought I would, so I think it's still in good condition. I can't attach a video, so I've included photos showing it in operation. Thank you. - Brand: FIELD FORCE - Model Name: Toss Machine - Adjustment Features: 4-level adjustment of launch distance and angle - Size: Height 23cm, Depth 43cm, Width 38cm - Hand Toss Function: Non-rotating toss function - Ball Compatibility: Soft baseballs, hard baseballs
