It is a very good training aid and it's a great price. Highly recommend it, if you seriously want to improve your putting. After practicing at home, I have been able to shave 7 to 10 strokes on my putting. No more 3 putts, and no 2 putts inside 10 feet.
I just got this putting mat today and right out of the box it laid flat, no wrinkles or kinks. The ball rolls smooth and it is exactly 11' x 3', and it comes with two cups, that you can move around. If you are looking for a putting mat to practice your posture and putting stroke, this is it.
Purchased for my husband for Christmas and he uses it daily! Great quality! Has held up perfectly, still looks brand new. Really great size all around a solid purchase. Totally recommend!
