Your JRMat has been a pleasure to use. Because of the depth of the artificial turf, I can practice on my deck without any problem or feeling of hurting my left elbow. I can hit down on the ball, thus encouraging effective ball striking.
It has been a joy to practice and get some good exercise without a trip to the driving range.
Thank you for making such a great product that makes it fun to practice.
