From the outset this is a sweet looking mech.
Pretty clean on unpacking. Completely brass with super slick threading.
The positive pin is spring loaded which makes for less adjusting when changing drippers.
The switch is sprung, slick and smooth. There is some adjustment to shorten the throw.
The locking ring isn't reverse threaded which can lead to loosening the mech but not to much of an issue. It is easy to use as it isn't smooth like a neme lock ring.
My only issue so far is when putting a battery in the mech.
18650 flat-top battery the setup it just about right.
18650 button-top battery there are some threads showing on the tube.

18350 flat-top battery the mech is completely collapsed and the vent holes are closed.
All round this is a very nice mech and I will buy another to patina for fun.
