Hi everyone.

I've been smoking regular cigarettes for a few years now (4-5).

I've ordered the black EVO from intellicig, and so far it's been great to me. Has a nice throat kick which is what is most important, IMHO.

However, I have a couple of questions I'd like to ask the pros here:

1) How do you know when a cartridge is over? I've found the EVO not to deliver a consistent throat kick, so I never know if it's over or not, and I'm afraid I'm ruining the vaporizer.

2) What maintenance techniques do you recommend with these e-cigs?
