My Kroma 217:
View attachment 969626
It's now my favourite 21700 mod, even though I only 3 incl. the 217
Its best points are:
-A really really solid battery door and hinge.
-The fire bar
The hand feel - it doesn't matter if I finger fire, or thumb fire both ways feel comfy
-The chip - I still prefer f0 mode. But running this in Coil+ is similar. The lil genie inside the chip sends a tiny pulse at the end of each fire. It also feels more grunty in Coil+ than it does in Power mode. Using a preheat of N in power, I run it at 25watts. Using a preheat of H then I'm at 24watts. In Coil+ I'm at 23watts.
The only downside this mod has, is it's weighty. It seems to be in the middle of the weight range for 21700 mods.
