Although I had read a lot of positive reviews of them at the time (about1.5years ago) I was disappointed. I ran the Gekko for a while, the one that I had was a total POS. I started having problems with the switch almost immediately with no moisture exposure. It proved to be true that it's not particularly water tight too boot. Didn't care for their computer either.

I really wanted to like that light, just couldn't force myself to though.
