well its not from running it dry because most of my juice is thin and it kind of auto feeds, I'm kind of dissapointed with it, I've been running cheap LR306s ever since I got my first reo, I got the first batch 5 for $30 dollars then I found another site that had 7 for $42 then found a coupon code which brought it down to 35 bucks. I don't know what the ohms are on the cheapies I never metered them I think the sites said 1.7ish but the point is I haven't lost one of those yet. I broke down and bought a couple ciscos from avid vaper to see what all the fuss was about got it monday and killed it tonight I'm sure it was my user error but that is the fastest I've killed an atty I guess I'll stick with the cheapies
