yes i have one but i don't take it canoeing anymore as it does not pack well.

so i take this one,in the photo it's just being used in a back yard test of a older model alcohol stove.the screen is from a MRS stove.the aluminum is thick but soft and can be bent into shape.it also opens up to form a circle shield around a burner.i can fold it over many times and being soft it is less likely to punch holes in the plastic food bags.
