I love my Mini Black Genius pipe! It cools the smoke so no coughing and it is soooo easy to clean with isopropyl alcohol. Just soak it a few minutes and wipe it down and you are ready to go for another few days. It is easy to carry in my pocket or purse and with the special carrying case I purchased it is protected at all times when I carry it. I highly recommend this pipe to anyone who likes to smoke.
