I bought this during lockdown so i could at least practice my putting while stuck at home. I soon realised that i was not standing over the ball and i was able to use this to improve this part of my short game. I strongly recommend this for anyone who wants to improve their putting as the feedback is instant. The great thing about this is it comes in a small bag so can be slipped into your golf bag so it can be used on a practice putting green at your local driving range or course.
