I had rotator cuff surgery recently so the only thing I can do right now is putt. I decided to purchase an indoor putting green so I can at least practice my putting. I went to my local golf store and was amazed at how cheap and flimsy the putting greens are. Even the assistant manager discouraged me from buying one. So I left the store empty handed and decided to search online. After I viewed all the online products, I decided to go with Big Moss. When I received my green and rolled it out on the floor I was amazed.This thing is like a real green.You can putt 4 balls into the hole, and even add a 5th with the right speed.If you are going to purchase a green,go with Big Moss. They have several models. I bought the original because I am limited on space.Trust me on this, the greens are somewhat pricey, but the quality is worth it.It even comes with a putting sword, and it has really improved my putting stroke. This little gadget is not a gimmick, it really works.
