I have the Rebel80 version and love it. It replaced my P1 and it's the only light I currently own. I can't recall ever feeling like I didn't have enough light with it. I plan on buying a nice 2xAA light soon, but I don't really need one. I've had this L0D on my keys for nearly a year and never had a problem with it. The finish is holding up pretty good. I use Energizer lithiums in it and they seem to work well. I consider the price resasonable, the size very good, the runtimes very good, and the modes good.
A couple things I'd like to see in a upgraded version would be a low battery indicator, the light made as small as possible, and of course a more effecient LED. I also wouldn't mind it just having low and high modes. I guess the strobe can come in handy in the right situation, but I've yet to need it or the SOS.
