I have had this one now for a few months and love it!
It is PURELY MECHANICAL with nothing to wear out or go bad. No switches. No wires. Nothing fancy, just a good, solid, hefty chrome tube and a spring-loaded bottom firing button. I pair it with an aClear nova knockoff
tank and a 1.8 ohm head. Hits like a freight train. As an added plus, it's telescopic so it can run any 18 series battery (18350, 18500, 18650), flat top, button top- doesn't matter.
And, did I mention that it is gorgeous? The chrome capped aClear looks like it was made for it.
Best looking, most consistent performing
mod I own.
