The twin combo system is perfect for my uses. I originally thought I only needed the golf mat itself, but that placed the ball on a different level than my feet and was awkward. By being able to move the standing mat anywhere I need compared to the hitting mat, I can place them any distance apart and use any or all of my clubs easily. The hitting mat itself has never moved when hitting balls, that concern can go away completely. The mat has some heft to it and it would take more than a golf club to make it move. As for storage, I believe the two piece combo is easier as well, since they can fit in a tighter space, taking up less room in the garage or shed.
I originally purchased a small, 12” x 24” hitting mat at a retail golf store, not knowing what I needed. The small mat moved after most hits, and began to fray after less than two hours. I returned it for a credit, but was only given a new mat, not a price credit. So I have a useless 12” x 24” mat here at home, it is absolutely no comparison to your product.
Your golf mat is what I really needed.
