Sakurai Boeki Promark Batting Toss Taimen II HT-89 with Rail

I bought this for my son, but he couldn't get the timing down, so he's only hit about 4 or 5 balls with it and hasn't used it since.
It's not that the machine stopped working, but rather that my son stopped using it due to his timing issues. There are absolutely no problems with its operation.
The adapter is included, and I've left 8 new AA batteries in it for outdoor use.

■Manufacturer's Description
Promark Batting Trainer HT-89
Practice hitting with realistic tossed balls from the front!
This single unit can handle 3 types of balls, so it can be used by the whole family and as your child grows.

● 3-level height adjustment! You can adjust the height in 3 levels using the height adjustment lever. Height and distance can now be easily adjusted. It can be used with an adapter or with dry batteries.
● Made with reinforced PP for excellent durability! Made with the same material used for car bumpers, it boasts superior strength.
● Practice hitting with realistic tossed balls from the front! When a person throws, the toss inevitably comes from an angle, but by using this machine, you can practice hitting with tossed balls from the front, which is more realistic to actual game situations.
● When used with the separately sold Promark Batting Trainer Net Continuous, you can practice continuous toss batting by yourself.
