I just received a LR 510 atty from iVape and I can't even believe what I was missing. I thought the tanks on my eGo were dope but wow, the hits I get from this thing are unbelievable. I only bought one so when this one dies I will be sad. I am going to buy more on my next order but I have a question. Is there any difference in life span and care compared to other attys? I have used a crap super mini, a 801 and the eGo tank attys so I have a little experience with them. All I know is that this is the best thing yet. Oh, and by the way I'm dripping into it if that makes any difference (I hate cart filler).
