To be honest, that is something I would likely use for my vintage 26" kettle with the steel handles or the IKEA handles on my big bullet centers.
I had been looking for something in silicone that I could wrap around the handle that would would be easily cleaned and stand up to the heat as well. Yeah, an oven mitt or leather glove work, but sometimes I just instinctively grab that hot handle regardless!
I have been known to shamelessly pimp products that make my outdoor cooking experiences easier!
