This is SSK's Technical Pitch. I purchased this used and used it for about 300 balls. The previous owner said they used it for about 100 balls, so I think the total usage is around 400 balls. I've included the remaining battery life in the 9th photo for your reference. I've included any major scratches in the photos, so please check them. This is a used item, so please refrain from purchasing if you are concerned about its condition.
