I have two O-light gun lights which I like, but I just bought a Baton, and already I hate it. Too many programming options which seriously detract from usability.
I got one of their little EOS lights, it's tiny, bright and kinda neat, but too small for EDC.
I’ve been using that light for a while now and my only complaint with the rechargeable model is that it gives you basically zero warning before it croaks. One day you’re good and the next day it doesn’t work at all.
