Slinger Bag Tennis Ball Launcher with 2 Batteries Included

This is a Slinger Bag for a tennis ball launcher.
I purchased this used last year and used it for practice, but due to moving, it has become difficult to secure storage space, so I am listing it for sale.

[Product Contents]
- Slinger Bag main unit
- Battery x 1
- Additional battery (purchased April 2025) x 1
- Battery charger
- Remote control key
- Smartphone mount
- Main unit strap
- Spare battery for remote control key

[Product Condition]
- Purchased used in March 2025 and used approximately 20 times (mainly on outdoor Omni courts), so there are scratches and dirt from use.
- The previous owner purchased it around 2020 and used it approximately 20-30 times.
- I have cleaned it to some extent, but some lint and sand from tennis balls remain that could not be removed.
- The original battery has weakened somewhat and only lasts about 1-2 hours in the fastest mode.
- The additional battery was purchased at the end of April last year, so I believe it has hardly deteriorated yet.
- All four screws for securing the battery are present.
- Sand has gotten into the main unit's handle, making it difficult to pull out at times.

Product shipping will be done on weekends and holidays.

Thank you.
