theyll probably upgrade it if you call them and ask. i know they have an offer if you have an old 510 from an original vaporshark theyll upgrade it for free, so id call for sureI am in agreement, really nice devices - I do love my dna30 and rdna30... One complaint, which I think is taken care of in the more recent models, is the 510 connection is not really the best. My dna30's got sunk in (it only takes like half a turn before whatever you are screwing on is tight, which feels wrong) and my rdna30's is bit loose with some tanks on it (some wobble a tiny bit).
