Pick-up only: Tennis ball launcher, Slinger Bag with various accessories

Items for sale:
● Slinger Bag Main Unit
(Purchased 4 years ago and used frequently. Primarily used on artificial turf with sand and occasionally on clay courts, so there are signs of use.)
● Genuine Battery
(This is the dedicated battery for the Slinger Bag. It was included at the time of purchase, so it may be somewhat worn. It should still function for about 4 hours intermittently. The image shows it secured with two screws, but there are actually four screws.)
● Genuine Charger
● Ball Pickup Tube
(This is the tube for collecting balls, but it is stuck in the extended position and will not retract. Sand is lodged inside. It may be possible to retract it with some force.)
● Genuine Remote Control
● Third-Party Remote Control
● Genuine Oscillator
(Used for oscillating ball feeding. Sand tends to get into the electrical connection part.)
● Genuine Smartphone Holder
● DIY Battery Pack
(Can be used for short periods of feeding short balls.)

Compared to other Slinger Bags, the advantages of this unit are the inclusion of a third-party remote control and a DIY battery pack.
The DIY battery pack uses a lower capacity battery, but the direction of the DIY approach is sound. If the battery becomes too worn, it seems like it would be a good idea to try using a higher capacity battery pack.

This item has been used for a long time and shows signs of use. Therefore, please inspect the actual item and confirm its operational status before agreeing to the transaction. Inspections can be arranged at Shikat Higashi or Hiokayama tennis courts in Kakogawa City on weekdays between 8 PM and 9 PM, at a court that can be secured.

I am willing to be flexible with other arrangements as well.
I will cover the court fees if the transaction is completed.
If the transaction is not completed, we will split the court fees.

Addendum:
Used for 2 hours on March [Year, assumed to be 2024 based on context, but not explicitly stated]. (Excluding time spent picking up balls) The ball feeding functioned normally for 2 hours.
Previously, I mentioned including balls, ball baskets, etc., but this is no longer the case. (March 30th)
