Love my Hcigar 2 tone Nemesis clone. Great machining. Haven't had no quirky switch, did you tighten down the switch post with some pliers? Heard some were shipped loose. Also read on facebook, that some were shipped with a spare spring inside the switch, once removed quirk disappeared. Can't go wrong with the Nemi clone. I also got in a buy on the FB site for the magnet upgrade but haven't had any switch issues since I tighten the post down.
Edit: Just opened up the switch housing, and there is a smaller spring inside the lager spring, took it out and has a much smoother throw now. Real smooth!! A ten second fix, just be careful not to lose the small locking key pin that keeps the insulator from spinning.
