I've ebeen using the same piece of Reynold's Wrap now for the last month, approximately 15 meals.
The performance to weight ratio is superb. Like Mr. Skurka noted, replacing it would be easy, as aluminum foil is everywhere. For as light as it is, I'd just bring extra if you are out on an extended trip. I do this anyway, by making my windscreen with 4-6 layers, folded over from one piece. It's not as flimsy as a single layer piece, and when the inevitable "burn through" happens, just fold it over, and no hole.
