Thanks! I'll definitely give those cartos a try. I did try Boge cartos once, and didn't like them at all, but I have no idea what resistance they were. It would be fantastic not to have the burning issue, and if I could get 15 refills on a cartomizer I would be thrilled! I make my own juices, and I'm using a 70/30 PG/VG base. I thought VG was harder on cartos, so hopefully I won't have any problem getting that many refills on them. I'm hoping that adapter arrives today. I'll order the new cartos, then I'll have a reason to continue stalking the mailman
I have been pleasantly surprised about how long these cartomizers are lasting. I have also heard that 100% VG juice is harder on cartomizers. I have tried cartomizers from V4L, Bloog/Volt/Halo, GoGo, Elite, and V2, all with varying results. Of those, the V2 ones are my favorite. If I get more than 5 refills from any of those, I consider it a win. At less than $2 each, it is a good deal. However, none of them have been able to match the longevity, consistency, and quality (again, tastes vary) of the SmokTek LR cartomizers. I have gone through 6 of them now, and each one got at least 15 refills.
They may perform better with your PG/VG juice, but at less than $2 each, I am happy if I get 5 refills from a cartomizer with my preferred juice.
One down-side is they are only ~1ml cartomizers, but I just carry two spares in my pocket (with condoms on, of course). The LR also burns through juice a little faster than higher resistance cartomizers - maybe 10% more. In my book, a very small price to pay (a couple pennies?) for an excellent, consistent, and reliable vape.
