Win a Zepp tennis sensor with the How It Works Issue 74 quick quiz

Zepp tennis racket sensor iPhone

You could win a Zepp tennis sensor by answering just one simple question based on the latest issue of How It Works magazine!

The Zepp Tennis sensor attaches to your racket and wirelessly connects to your smartphone via Bluetooth. An app will then measure the intensity, consistency and power of your game and give your guidance to help you improve your skills. The sensor tracks where the ball makes contact with your racket to help you hit the sweet spot, and the app can replay your serve in 3D from any angle and compare your skills to a pro player.

The answer to our quiz can be found somewhere in issue 74, in which we uncover the incredible technology behind future super soldier armies, explore the history of the bloodthirsty Vikings, take a tour of Yellowstone National Park, plus much, much more!
