Pros :
Cons : i prepared my glass with the foil, not aware it was the foil making me ill at my stomach, because my husband was cutting trees down, and smelled of gas. after changing my shirt, i finally smelled my pants, then realized it was the foil that smelled like gas. my husband also said it smelled like old gas. i stayed ill 3 days because of foiling with this product, and only used about 1/2 a package. will not use it again. not worth it! i know the more expensive does not have this effect. just wish i had realized it sooner. would have never thought the horrid smell was coming from the foil, though.
