Hi jwyj,
Just put some thread grease around the button and click it a few times and the movement will become more fluid.
Does the button need to be removed to add the grease?
I am thrilled with my Firefly. It's a shame Joshua didn't go into production with this light because it's a beautiful light that's as functional as it looks.
Joshua you nailed it with this light!
I have Fenix 14500 batteries and can't tighten the head down all the way but the light still works. Anyone else using Fenix 14500 and have the same results?
