Honestly, I could totally live without it, but I find it useful when dealing with heavier dishes in the oven (that a towel/cloth pot holder might not feel quite as secure for), It’s especially useful when operating a hot grill (pouring charcoal from the chimney, arranging the hot charcoal on the bottom grate, grabbing the lid handle after 15 minutes of high heat).
