Bluetooth-compatible Technical Pitch Ball M-ball - Brand: SSK - Model Name: TECHNICAL PITCH - Size: M-ball - Bluetooth Function: Compatible - Box and instruction manual included Thank you for viewing. I purchased this used, and it has been used for less than 1000 pitches. The previous owner also stated they used it about 15 times, with less than 1000 pitches, so I think it still has a lot of life left. Please check the fifth photo for the battery level. The box is quite damaged, so please consider it as an extra. This is a used item that has been owned by two people, so please purchase only if you understand this.
