Overall a good light. Feature-rich. Easy to operate / select secondary lights. Momentary on in all settings, High medium and low on all lights VERY handy options). Red LED great for night use and signaling (along with the green). Blue "blood-tracking light is very effective for that and other fluids. Most versatile tactical light I've found. NEVER without mine.
Pros: Multi-color, low power usage, waterproof, hi-lumen main, easy to use.
Cons: Bezel should be more rugged. No strobe option.
