The Pure2Improve Golf Putting trainer is scientifically designed to simulate real putting conditions. The putting trainer automatically returns the ball on good putts while rejecting missed putts. Precise putts are rewarded by holding in the slot. The difficulty can be ramped up (literally) by clicking up the height of the ramp to further test your accuracy and pace. The trainer folds virtually flat for easy storage and transportation. For use indoors and outdoors and on a multitude of suitable surfaces. Proven to improve pace.
