Yup, I've been having contact issues also. Just emailed Fenix-Store about it.
For example, sometimes when I'm ramping the light will just go off or behave strangely (e.g. flicker or jump around in terms of light level). Also, when I twist the light on it never goes straight on. Instead I get a little pulse before it comes on constant. In other words, every time I twist (no matter what level it's set at) I get a little on-off-on sequence in quick succession. Occasionally I'll also have trouble twisting off. The light will want to stay on despite my having twisted off.
I've tried opening up the gap in the split ring a bit without much success. In fact, the split ring fell out once or twice. What is it supposed to latch onto when you put it back on? The spring underneath it? At any rate, while the ring was off I used a toothpick to gently poke down the spring that the ring depresses, and I think it might be the culprit. It definitely sticks. There seems to be a burr on the spring that's catching the side of the light. Not sure how I should go about fixing it. Maybe I'll try what Stillphoto and Beamhead suggested once I have a chance to attempt to remove the bezel.
Anyway, I really like the light, but I have to agree that in my specific case the switching mechanism isn't as reliable as it should be. Hope there's an easy solution.
