Keep fighting the good fight, Bert! I salute you.
I think it's also important to mention that the blu works wonderfully with a 306 drip tip too. I don't know how the cartos are, but I know that the flavor is AMAZING with a drip tip on a blu. When I got my 510 drip tip, because of how good the blu is with a drip tip, I was expecting it to just blow my mind, but it doesn't. I don't regret buying my 510 drip tip at all, but it should be noted that the blu with drip tip gives the best flavor. The 510 atty just runs too hot, I think. Oh, and anybody who says that the blu is bad for dripping because of the auto battery can shove it because they obviously haven't tried dripping with it and therefore know NOTHING about it and should keep their mouths shut. The 510 with CARTRIDGES gives me MUCH more trouble as far as flooding and getting juice in the battery hole and threads is concerned than the blu does. Getting juice in the battery is always a concern when dripping, but it is much more of a concern with the 510 than the blu(using auto batteries in the 510, obviously, as the manuals have no hole).
Hey Rege, if you'd read the thread, you'd notice that the OP has already found a solution to his "problem." You'd also know that there was a lot of crap going back and forth about people making unhelpful posts just like you did. Like Bert said, everybody knows you can send the blu back. It says so right on their website, and it's been mentioned in this forum more times than I want to remember. Posts like yours contribute NOTHING. Congratulations for wasting forum hosting space regurgitating crap.
