UNREAL!! I bought 4 packs (5 in a pack) of smok tech 5.0ohm carto's from madvapes on July 27, in my posession July 29th. WOW..and shipping was only 15 bucks too and came by fed ex! My total US was 46 bucks. I would say not bad! Considering 2 days it was here from NC- thinking that is North Carolina? Anways, am about to try these bad boys on 6 volts on my Omega mod. Got some juicy clear Canadian Full Flavor about to rock! These carto's could not have showed up at a better time. My 3.7v batt died yesterday, after 3 full days of vaping. So I was all bummed cuz I had to start vaping off my 510 passthrough..but sure enough, madvapes to the rescue! And my new HV carto's are ready!!!
