When I first received the Tee Claw I noticed that it was a very unique and clever idea. This product the Tee Claw can almost be used anywhere such as carpet, turf mat and short grass. When you are setting up the Tee claw it is very simple you attach the cord to the bottoms of the Tee Claws and spin the claw into the ground to make sure it does not move. The reason the Tee Claw is very unique and helps you is when you put the ball on the tee you can see the line that your swing should be on to help your swing. More than helping your swing it can help your putting if you put two Tee Claws next to each other to keep your putting in alignment.
