A quick comment on the Tauren mech boro
mod :
The vape is better than I expected with the X chip (mosfet).
I've done some tests and it hits almost as hard in mosfet mode as full mech, especially when you screw down the battery cap (hard!) with the tool provided.
Reminds me of the Luxotic BF.
I'm not keen to run it in full mech mode too often - too many variables with boro rbas.
One major negative is that it doesn't sit flush on a flat surface. It rocks a bit because the base is slightly convex. I think I can see why - the design of the fire button assembly puts pressure on the centre but not evenly. Anyway, I'll be mangling the thing soon, so a bit of sanding on the base won't be a problem.
