Custom Grill Master BBQ Mat - Personalized Father's Day Gift vs Tool Mat: which is safer?

Where these two actually differ

• We flag Silicone degradation and leaching at high heat, Coated fabric off-gassing and thermal breakdown, Microplastic or coating shedding into food and Personalization ink or dye safety on the GRILL MASTER 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 GRILL MASTER.
• The GRILL MASTER is Silicone or coated fabric mat (composition unspecified) where the Weber is Silicone mat or rubber composite, which is most of the difference in these two grades.
• The gap is 65 points, wide enough that this is not a close call, and the Weber is the one to buy.
• We are less certain about the GRILL MASTER grade, at 35% confidence against 72%, because it discloses less.
