I am very pleased with this headlamp. Generally I use it on the lowest red lens setting for reading maps at night. The battery life is outstanding on this setting. I really like that the lenses are interchangable, and it's a physical slider that changes from lens to spotlight, as opposed to having separate LEDs. This makes it possible to turn it on and off either way without having to cycle through numerous settings. The white lens and boost modes are surprisingly bright. It's like having a car's headlight with you. Very happy with the construction- good at keeping water out, shock proof/resistant (haven't dropped it enough yet to say 'proof' haha) The power switch is easy to use with gloves, but not to the extent that it turns on and off when nudged. Price seems reasonable. I'm always a fan of lower prices, but I got it on sale so I'm not complaining too loudly!
EDIT: The belt clip is very sturdy and well built. It's actually kind of a pain to get it back off of webbing - which is a good thing!
