I have had this great product for over a year. There is NOTHING you can do for your game that will improve your confidence more than making 100’s of 3, 4, 5, and 6 foot putts. Very well built and should last for ever. One direction rolls a little faster than the other. Easy to set up to make right or left breakers. Investment is less than one green fee at a high quality course! If you have tile/hardwood just put it down and start draining putts. I put a log on the wall and track how many I make. 5 minutes of deliberate practice will cut way down on three putts and build your confidence.
