16 inch x 13 inch BBQ Grill Mat - Non-Stick, Reusable, Perfect for Gas, Charcoal and Electric Grills, Even Cooking and No Mess, Ideal for Steaks, vs Tool Mat: which is safer?

Where these two actually differ

• We flag PTFE thermal decomposition and fume risk, Coating degradation and microparticle shedding, Fiberglass substrate exposure and Leaching of coating binders or additives into food on the Eco By Naty and not on the Weber.
• We flag Silicone degradation at extreme heat and Off-gassing of volatile organic compounds (VOCs) on the Weber and not on the Eco By Naty.
• The Eco By Naty is Unknown non-stick coating; fiberglass or silicone substrate presumed where the Weber is Silicone mat or rubber composite, which is most of the difference in these two grades.
• The gap is 60 points, wide enough that this is not a close call, and the Weber is the one to buy.
• We are less certain about the Eco By Naty grade, at 35% confidence against 72%, because it discloses less.
