got some of the low res. 2Ω 510 cartos. very nice. i have a tendency to burn most cartomizers post-haste (they don't call me the Carto Killer for nothin'!), but got my first to last me a whole 24 hours. the 3Ω variety are great as well! those last me a couple days easy. needless to say, about to order more.
though, i would really love to see something in the middle. like 2.4 or 2.5Ω. that's my sweet spot on a 510/eGo.
Thanks.
