I respectfully disagree. Horizontal, bottom coil cartomizers (i.e. Bloog, Volt) do not have this issue. There is no wrapper around the coil to get burnt. I rip mine apart occasionally for various reasons. There is a cotton wrapper around the center tube, but it makes no contact with the coil, which is sealed in the bottom. If you yank out the filler and leave that wrapper on you can actually use the cartomizer to drip as well, cheaper than an atomizer. I usually vape these on my eGo with a 510 to 901/808 adapter, works great. Get about 5 refills with GJ before the flavor change, clean and repeat.
C8se, Aren't Bloog and Smokelessimage pretty much the same since they are both retailers of Shenzen Kanger? I have tried their cartoz when Kanger sent me a few of their ecig kits to try and to be honest, they were not bad. Just couldn't vape the juice that was in the cartoz because the nic was way too high so I gave the kits to my sister.
I will order some blanks from SI and give them a try, too bad they don't make them in 510's because I really hate using adapters on my Precious. Do you know of any other companies that carry this same carto besides Bloog or SI? Also, I hope these cartoz are not like the G4's, already tried those and they sucked rocks.
