DNA Chip is awesome.
Efusion, I love mine. It's small, the 3s 1300MAH battery last a good amount of time in the 50ish watt range. It is one of the classier looking premade DNA 200s. I would love one with a wood veneer in place of the carbon fiber. It has a firm 510 spring.
only cons I can think of is if you everso light press on the buttons there's a little mush. Not that noticeable during a normal button press. Vaping at the high wattages suck ALL batteries down fast no matter what mod.

For comparison, a Dual VTC5 in series which would be as used in the Seigely or IPV mods Comparing as capable mods available, I realize the battery differences as one is 2 in series and the other is 3. The whole battery life argument is the DNA200 mods compared to these mods mostly.
