Reason for listing: I used this for my eldest son's hardball practice and my youngest daughter's softball (J-ball) toss batting practice, but I no longer need it, so I'm selling it. Selling points: I think this is good for getting a feel for timing and practicing storing power for hitting ⚾️. It comes with an extension lane. Missing parts: As shown in the fifth photo, the claws that connect the lanes are broken, but the balls can still be used smoothly. See the seventh photo for details. Operation check: Operation has been confirmed with both the power supply and batteries. I will send the items in the eighth photo, so please consider purchasing.
