Agreed - this bit especially could use some work: "Yes! Joulies are perfectly safe when used properly, and in fact make drinking coffee safer than usual by reducing the risk of burning your mouth." (Emphasis mine) The whole "it's actually safer because burning your mouth is unsafe" isn't very comforting, and the "safe when used properly" clause makes me think "what happens if I dont' use it properly?" The fact that the inner material is proprietary and is somewhat of a mystery doesn't help either. Still a very interesting idea, but I think the early-adopters and overall target market for theses things overlaps largely with more conscientiousness food shoppers who want to know exactly what's in the food and drink they buy.
