A few months ago, I got a basic ego starter pack and eventually upgraded to an Innokin VTR with a Kanger protank 2 (w/aerotank base) so I could rebuild protank coils (great choice, works waaayyyyy better than the factory coils). Now, this is all fine and dandy at work, where something easy to use and durable is appreciated, but I recently decided to make another upgrade and get an rda and a mechanical mod for at home use to cloud chase and for the flavor. My question is, what exactly should I look for in a mechanical mod? I understand the difference between most RDAs, but mechanical mods just seem like they all do the same thing and just look different...what am I missing? Also, since I'm on a budget, I'll likely be going with clones, so are there some made better than others? The RDA I'm most interested in is the Magma, if that helps at all.
