ATEC Casey2 Pitching Machine Thank you for viewing. This product was purchased for my son's self-practice, who was playing elementary school soft baseball, and was used at home. It supports J balls and M balls. The usage period is about 3 years. It has a variable speed mechanism, and although it wasn't used every day, it was used for batting practice, bunting practice, and fielding practice (ground balls, fly balls). There is some aging, which is within the normal range. As shown in the photos, there is a scratch on a part of the power cord, and it has been reinforced with vinyl tape, but there are no problems with its operation. - Brand: ATEC - Model Name: Casey2 - Type: Pitching Machine - Adjustable Speed: Yes
