Love them, they do the job and wash off easily. Not sure about BBQ use, a those temps are much higher, but for kitchen ovens, racks, hot dishes, taking food from the microwave, they are perfect ! I have several sets and they all look as good as new, after 5 plus years of use.
I have bought several pairs of these for myself and as gifts. Cloth oven gloves invariably look grungy after a few months, but these look as great as the day I bought them. My husband has used them to handle food in the smoker, but any black smudges wash right off these gloves. They are also so well insulated you feel no heat at all through them. I love this product.
