We are working out a couple of small complications to better improve the KC1.

I hope Vortex mean that!
I bought four KC1's awhile ago, two KC1s did not work out of the box!
The problem with the two failed lights was due to insufficient contact being made between the body and two small 1 millimeter diameter metal plungers within the bezel (head). The insufficient contact was actually caused by the body interior (which made contact with the plungers) having been "ground down" by slightly raised screw heads contained within the bezel.
The raised screw heads prevented the body from making contact with the plungers, and they also cut into the body interior whenever the bezel was screwed down in an attempt to switch the light on. When I first opened the lights, I found metal shavings within the bezel which were the result of the screw heads cutting into the body!
These screws within the bezel were not sufficiently tightened down. However, on tightening them down a bit, they caused the plastic plunger support parts to crack open beside the screws!
With the screws either removed or tightened down, it was found that the lights still did not work as the body interior had been "ground down" by the screw heads and the body could no longer push the plungers down far enough to activate the light!
I don't know how long the other two working lights will continue to work. I suspect that the constant abrasion, and scouring that is caused by the two small plungers rubbing against the body when operating the light will eventually wear the body interior down. This will eventually lead to insufficient pressure being applied to the plungers due to lack of interior body material, and consequently the lights will fail to work!
Bad design, and bad quality control!
After I contacted the dealer who supplied the faulty lights, my understanding is that a substantial number of the last batch of KC1s had similar problems and had to be returned to the manufacturer.
Overall, I am not happy with these lights!! /ubbthreads/images/graemlins/Christo_pull_hair.gif
