Can you beat my serve speed? Testing the Babolat PIQ Robot

I invited my friend Matthew to test the PIQ Sport Intelligence sensor. It's an advanced sensor which I wear on my wrist. It's really comfortable and does not interfere with my game. I can see my serve speed while playing, so I get some vital information when trying to win the game. 

Other interesting features are available via the PIQ app - Spin rate, Forehand & best stroke speed as well as best rally information. Check out my top speed - can you beat that? More information are on the PIQ website

PIQ provided us with the tennis sensor for free so that we could write this review.
