The Robo Cup was the winner of the Best New Product at the 2009 PGA Show. It slips into any putting green cup, and returns the ball to you once you've made a putt (returns up to 10'). The supplied Caddy Cord helps to corral errant putts into the hole, to make your practice time more efficient.
*Note: To be used with the BirdieBall Putting Green, be sure to purchase the Robo Cup + Shim Package so the Robo Cup will fit! Purchase here: Robo Cup with Shims
