I'm quoting you because, yes, the batteries do overheat the cartridges (granted, dependant on how frequent and deeply you draw), and I got second degree burns on my tongue and throat from them (verified by an ENT and not do to any battery 'defect' since it occured with all three batteries. I'm glad someone finally mentions this because when I posted what happened to me, there was an influx of people saying no no that can't happen. Well, it can, it did and it's something people should know about. Thank you.
Yeah, blu's truly are of the poorest quality. I'm really glad they put who manufactures the liquid on the packaging... if it wasn't for that I probably would have stayed in that abusive relationship for a little longer than I did.
Sorry for what happened to you. That's almost worth suing over. There's no telling what else goes wrong with these things that could really mess your lungs up that aren't as noticeable and extreme as your case. If ecigs are ever made to be illegal, I'm sure blu will be to blame.
