So, the Walfos Silicone Trivet Mats are kind of on the thinner side, based on what we've found. Some folks mentioned that when they're dealing with super hot stuff, like cast iron pans, one mat might not be enough to keep your countertops safe. A lot of people end up stacking two mats to get better heat protection.
The manufacturer says these trivets can handle temps from -104°F to 446°F, which is pretty impressive. They'll definitely help protect your countertops, but you might want to be careful if you're using really hot or heavy cookware.
On the plus side, they're made from food-grade silicone and are BPA-free, so they’re safe to have around food. They're also non-slip, which means your dishes should stay put. But, if you're thinking of using them to move stuff straight from the oven, be cautious—it seems they might not hold up well for longer periods of heat exposure.
They’re versatile too! Besides being great for countertops, you can use them as drying mats, jar openers, or even coasters. And since they're dishwasher safe, cleaning is pretty easy. Just keep in mind that their honeycomb design might need a bit more time to dry completely after washing.
Overall, while they might not be the thickest trivets out there, they're multi-purpose and easy to maintain. For tasks that involve moderate heat, they should work just fine. If you need more heat protection, just double up, and you should be good to go.
