Heavy-Duty Golf Hitting Mat

I bought the 21mm version and was pleasantly surprised by the quality. I found it works much better on a hard surface. I hit balls from my patio into my lawn. With a hard surface below, you will know every time you chunk it and every time you hit it perfectly. In my opinion, this improved my skill and I'm less likely to chunk it on a fairway. A compact dirt area may have the same effect. I found that it was just too forgiving when I placed it over grass. I also have been leaving it setup in the backyard. So far it’s been standing up well to the rain and sun. Overall, great value for the money!
