I've carried stuff daily from Streamlight, Fenix, Maglite, Coast, Surefire, etc.... The only one that has ran 100% of the time is Surefire. For the money, Streamlight is tough to beat, but will wear out with hard use. Fenix has been pretty temperamental for me, Maglite is bulky and low performance, and my Coast stuff performed poorly outside of 20 feet or so. My current favorite is my Surefire E2D.
