Welcome to ECF Brady.
I'm a bit surprised no one has taken the time, since yesterday, to at least say hello. It is IMO, the "responsibility" of long term members to welcome new members. ;-)
Anyway... moving on to mechs. A few things you need to know. Mechs are nothing more than unregulated battery holders with a "switch". The available output, all else being equal, is based on coil resistance and battery available amperage... with no real "user control", but those two variables.
Fitting a standard type, production atomizer, like a glasso or clearo with pre-built "common resistance" coil heads, on a unregulated mech may actually provide a lower quality of performance than if you had used a VV-VW APV (or Kick VW insert in a tube mech), where output can be boosted and controlled.
The point is - especially if you intend to work with rebuildables - you need to spend a bit of time learning the basics of Ohm's Law, in particular the parity between resistance and amperage. Click on my second sig line hyperlink if you have a greater interest.
