What problem are you trying to solve?
I'm trying to solve the problem of "I don't have it."
AHAHAH!! I put down a shemagh the other ,and said out loud to my husband, "I don't need one just because all my friends have one." LOL! Heavy duty aluminum foil sounds WAY more justifiable to me, especially when aluminum foil is on your shopping list already. The real question is, why wouldn't you upgrade?
In all seriousness, is there really a downside?
