it’s good,but….
This review is from: Surefire A2 Aviator Tactical LED
I’ve had this flashlight for about 6 months, and also the central (and bright) white light has stopped working. I disassembled it and discovered a large amount of corrosion built up on the contacts for the white light – no idea where it came from as this flashlight has not been exposed to water. One other member of my unit reported the same problem with his. It could be a design flaw, be warned.
