I just want to say I love this product! I have never been able to find such a versatile, usable, easy-to-use game aid in my 15 years of DMing. It folds up neatly so that I can fit it in a simple folder, I clip a couple dry-erase markers to it, and I'm ready to go. I was originally worried about the size, but it is more than enough for what I need. You could even buy two mats (they're cheap enough) and use them for large scale tactical battles or Warhammer 40k minis. If you are considering buying this product just buy it. I have no regrets.
