Edit: Customer service from Melee Mats is fantastic and after I reached out to them for tips for removing the wrinkles, I was sent a replacement at no cost. It just arrived, so I have not had a chance to use it and verify that it will not develop the same issues, but I wanted to update my review in light of the customer service provided.I will revisit this review in a couple months of play to see if it earns the five stars or if this one wrinkles as well.Original Review:I purchased this mat just before we went into quarantine and the first time I used it, it seemed great. I stored it according to the instructions included, and when I took it out to use it a couple months later, it had developed a couple of wrinkles in the lamination. I was able to smooth them out to just ridges, but when I unrolled it to use at the next game the wrinkles had multiplied. I have used it for less than six games and it now has so many wrinkles that it is hard to erase and barely usable.I would not recommend this product unless you intend to lay it flat once and never move it again. Even then, I cannot vouch for it because I have not been able to test it in that manner.
