If you want to improve your tennis game you could hire a fancy coach, or you could get this electronic smart racquet which will let you analyze your swing in minute detail.
Loaded with electronic sensors, the Play & Connect racquet can determine everything from your service velocity and racquet speed, to exactly where on the racquet you’re making contact with the ball. Most importantly, despite all of the fancy electronics, the racquet has the exact same weight and balance as a regular racquet.
