This is a pitching machine that can be used for self-practice in baseball. It is compatible with perforated balls, and automatically feeds balls when placed in the upper basket. Can be used both indoors and outdoors. No box, uses only single batteries. My son no longer uses it, so I am selling it. Operation has been confirmed. There are minor scratches from use, but it works without any problems. Please check the condition in the photos. * 10 balls included.
