Some of the links on this forum allow SMF, at no cost to you, to earn a small commission when you click through and make a purchase. Let me know if you have any questions about this.
The Q-MATZ I use that I bought from Todd Johnson/A-MAZE-N look very similar to these. I've used mine only for smoking cheeses and beef jerky. None of that ever melts into of falls through the racks anymore.
