You are not missing out on anything with this putting green. It includes infinite possibilities for putting, and it lays flat all the time. One thing that is not commonly advertised is the there is about an inch and a half piece of foam on half of the green, but this is manufactured perfectly to ease into a very very slight uphill putt. With the speed and reliability of this green, you do not even notice this piece of foam. In fact, I am glad that this is here because I love the satisfaction of seeing a ball drop into the hole. Overall, this green rolls true and runs flat, and with break snakes it is a great green. Also, I purchased a separate chipping mat and 10 “almost golf” chipping balls for indoor chipping. The green also comes with two of these chipping balls, and I am very happy with them as they react and spin the same as a regular ball, without putting a hole in your wall. Overall, I am very satisfied with this purchase and would 100% recommend a Big Moss putting green as they are superior quality and practice.
