I develop training equipment for "table tennis rallies" for you.
A played ball is to be returned back to the player.
This ball will not only once - but -
when played in a controlled manner,
come back to the player several times.
As a result, "single-player ball rallies" can be trained which enable a challenging topspin training.
Whether at home-TRAINING or in the CLUB - they rediscover table tennis.
