For the pot I use for sous vide I have towels covering it + a chopping board underneath - as you can imagine it looks pretty bad but I’ve seen this insulation band and mat and wondering if anyone has tried it?
Why spend a lot of money on a single purpose item? I got some 1’’ rigid foam (pink) from Home Depot, and I cut a base and pot covers, from it, and I use a couple of big bath towels to wrap the pot. I have posted this info here before. Look it up.
