Me thinks you have convinced me to try it.
I liked mine okay. I haven't used it since I got my reo, and I'm not sure where it is. But, I'll eve rurally pick up another if I can't find it. It's not bad. The build is pretty janky
it's about like a vivi nova or evod rebuild except that the grounding leg kind of just gets shoved to the side instead of actually getting captured anywhere. Then again, I could be missing something. Also, they seem like they'd work better if you actually use NR wore for the legs.
The only real caveat is that you have to be picky about your bottom seal being really dry. If you go to take if off of a mod and the wrong section spins, it can come apart and dump juice all over everything.
Still, I have 3 cartomators that I haven't used since I got into RDAs and my reo. It'd be nice to be able to use them again.
I think they're worth a try.
