We are a dynamic startup straight from the heart of Stuttgart. Our goal? To rock the tennis world with high-quality and innovative products!

We dream of setting new standards together with you and shaping the tennis landscape – all developed in Germany, for tennis players worldwide!

Instructions:

Step 1 – Setup:
Remove the weight base and tennis ball from the case, unroll the cord, and position the base with the eyelet facing the direction you want to hit, on firm ground.

Step 2 – Safety:
Make sure there are no people or obstacles within a 15-meter radius.

Step 3 – Start playing:
Hold the tennis ball in your hand, ensure the cord is free of knots, and hit the ball away using your tennis racket. Thanks to the elastic cord, the ball will return to you – the game can begin!

Step 4 – Pro tip:
Hit the ball with a slightly higher arc for a more consistent return and better flow. For players who prefer not to hit the ball too hard, we recommend shortening the elastic cord to 3.5 to 4 meters. You’ll find a tutorial for this on our YouTube channel.

What you should know:

Our tennis ball is specially designed for maximum durability. Still, even the toughest ball has its limits. With intense use, the lifespan of both the ball and the cord may shorten. No worries – we’ve included spare cords for you, and spare balls are available in our Amazon store – just as easy to replace as the brush head of an electric toothbrush! Tutorials for replacement are on our YouTube channel.
