running the Uvo Systems Aqua on my mech right now, dual coils, quad juice channels, adjustable air and juice control!! Haven't had better to date. Also have the Russian and terminator-C. The Aqua blows them all away. Going to play with the Fogger V3 next. Then once my Hemp fiber arrives will re-wick everything and try it all again. Lot of mech mod worthy rba's and rda's to choose from. All depends on what style trips you trigger. I like bottom coil tanks, full metal SS tanks. All the flavor or a dripper but with juice on board.
