I finally just received this in the mail yesterday. I haven't been able to use it yet, so i will have to update my review afterwards. So far, from just seeing it, it looks pretty sturdy. The size is just about right to fit on an average gas or charcoal grill and still have room to cook beside it. I intend to use this on my next family camping trip to cook for my middle daughter. she doesnt like the black lines from the grill on her food. i will update after i use it.
UPDATED
My family and I just went camping last weekend so I was able to use this. I used it on the grate over the firepit at night for cooking a late night snack of hotdogs and fried bologna. That is my kids go to food when camping. The grill mat worked very well and I will be using it again. Cleanup was easy. I was able to wash it in the sink with the other dishes and there was no damage to it from the water. I think this will for sure be a staple in our camping routine because my daugher actually ate and didn't have to complain about wanting the black lines cut off of her hotdogs.
