Sharpen your putting skills with the Athletic Works Automatic Putting System. This gravity-powered putting green features 7 feet of realistic green turf, a raised regulation-size hole, and a unique mechanism that sends every made or missed putt right back to you. Due to the elevated hole, if you putt a little too soft, the ball returns to you to try again. Putt a little too hard and the ball falls into the rear channel and returns to you to try again. Make the putt, you guessed it, the ball fall into a trough and is returned to you to celebrate a little... and putt again! The Athletic Works Automatic Putting System is great for use at home, the office or parties.
