Not Yet... I have not used it yet, because I am so happy I can now take the Journeyman with me everywhere I go!!!! I had a problem with dropping my PV, and sitting with it in my pocket, and now... No issues! I will take the Liquid Luggage out this weekend to my gigs (I like to drip at my gigs). Now I do not have to carry a little plastic bag with all my juice with me!!!! I am sure it will work great.
