Review on The Ultimate High-Temperature 27 5 Grounding Cord: Optimal Safety and Durability by Larry Morris

This is a nice heavy duty anti-static mat for my computer. I also use this https://smile.amazon.com/gp/product/B071J61CSV/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 to ground the pad to the outlet. The edges are still wavy after 9 months. At first I rolled in the opposite direction for several days, but this did not get rid of the curl. I then put it on top of my underfloor heating in hopes that the warmth would help, but that wasn't any fun either. I resorted to using command strips around the edges to flatten it out a bit. Next time I would look for a different brand.
