The Racket Sports Set with VIVE Tracker from HTC includes a paddle and a racket designed for the HTC VIVE, a VIVE tracker, and a digital download copy of Virtual Sports. With these items, you'll be able to enjoy virtual ping-pong and tennis against online opponents or against the computer. The tracker attaches to the center of the rackets, with a slightly recessed design, that keeps an even weight balance no matter which way you hold the rackets. Moreover, rubberized grips ensure you won't slip up on a serve, and a lanyard keeps the rackets from flying away during intense competition.
