I bought a Magma a while back, and use 3mg or 6mg juices in it, when I bother to use it... Yes, the flavor and vapor are amazing, but I guess I'm just too simple to bother with it very often, and I'm not a cloud-chaser
The flavor from my RTA's (Russian 91%) is just as good, and I don't have to carry a bottle of juice from room to room... I guess that makes me a solid tank-guy, lol.
The RDA (Magma), to me is akin to a good pipe or after-dinner cigar... worth the effort if you are "stationary", even though it does hold quite a bit of juice in the tray/well, but I'm way too active, which is why I prefer tanks or RTA's (rebuild-able customization, but still have juice capacity, and less "mess").
