excellent product. i have personally put hundreds (maybe thousands) of hours on this light and still works like new. i have droped it off a cliff, put it through the washer...and dryer, worn it in storms, freezing cold and 120+ degree weather. i still havent managed to find a way to break this thing without actualy bashing it with a hammer. petzl, my only request that i can think of that would make this the ultimate headlight is the ability to take the light from flood only and focus it to a spotlight, or possibly a second light for spot light. the red/white combo is awesome so when i dont need tons of light i dont destroy my night vision.
