yeah, i havent had a problem (knock wood) with my jb3's (both new), i was just looking for a preventative that was lo-pro. as hot as it was that night stealthing the digable planets, i was probably more concerned then i needed to be... then again, i was DRIPPING sweat at 11:30 at night and doing a lot less work then my lil ol jb3 (pet pet).
i think my main concern was a festie type stealth occasion outdoors in the florida heat... probably best to bring both of the jb3's that way in case one goes wonky i can plug in the other one.
