by "upgrade from my magma"...what does that mean?
its well made, single and dual coil, liquid resovoir, selectable air draw options...
what upgrade are you looking for. as a reliable atty thats easy to build, it has top flavor delivery, for those that dont mind a bit of a restricted air flow, it gives you that also.
if you are looking for a cloud chasing dripping atomizer, there are those out there, and its not necessarily an upgrade, just delivers a different style/type of vape...
