It automatically and quietly returns the ball to the addressed position, allowing you to concentrate on repetitive putting practice. It's 2.7m long. - Model Name: DAIYA AUTO PUTT 532 I want to practice putting every day, but it's hard to concentrate if the ball doesn't return to me. There are various putting mats that return the ball, but they are either expensive or the sound of the ball returning is noisy, so they all have pros and cons. This putting mat is quiet when the ball returns, making it ideal for practicing indoors. It's also 2.7 meters long, so you can practice longer distances. I bought it for 10,000 yen.
