My dad loves to play golf so much so I gave him this on his birthday. Our house has a little bit of extra space and we had it installed there. When it was installed, it had no wrinkles on it which made the ball glide into it very smoothly. My father knows a lot about it as his friends also own some grass, so he immediately knew that it was a very high quality which made him very happy. I've never seen him that happy and even almost teary eyed because he now has his own mini golf course at the comfort of our home. Thank you for this amazing product!
