Well, I don't know about the rest of them, but I drip and drive.
But I don't recommend that for everyone.
For those that aren't capable of dripping and driving, a cartomizer may be a necessity.
I just wish that the burning filler material was not an issue anymore.
Not that I have burning cartomizer filler material, because I am experienced.
Just that newbies are not, but I guess some might consider it a small price to pay.
I have not had a burnt filler issue with the 510 cartomizers... maybe you should give it another chance
