The Ballkeeper is fully automated. The pressure is adjustable between 10-20 PSI. Any natural pressure loss in the Ballkeeper is automatically compensated for and topped up to the set value.

The perfect target group would be tennis players who want to maintain the pressure of the ball for a long time. The ball is then only replaced when the felt wears out.

The regeneration of flat balls is very time-consuming (several days/weeks) and depends on the quality of the balls. The Ballkeeper is highly effective at maintaining pressure if the balls are stored immediately after the game.

Extended lifespan, waste reduction, reduction of single-use packaging.

- Longer ball lifespan means fewer newly purchased balls.

- Less packaging (aluminum, plastic).

- Fewer resources needed to produce new balls.

The Ballkeeper itself has a long lifespan as it is made of robust materials. It can be used for several years, which keeps its ecological footprint very low. The battery lasts for several weeks.

The Ballkeeper is fully automated, no air pump or additional devices are needed, and the Ballkeeper also has a mechanical pressure relief valve.
