Black Diamond Cosmo 350-R Headlamp Octane

Great item works as I wanted really good on batteries great product. Would recommend it to anyone.

Decent lamp, different brightness settings would be nice.

Brilliant light. Works well, and comfortable to wear. Hasn't let me down and I actually ended up buying 2 so I have one in the car also.

Confusing instructions. Saw videos on Google, didn’t helped. Went back to REI store. Learned key functions. All in, it was 11/2 hrs to learn how product works. Doubt manufacturer has ever used focus groups.

This was a great buy. The things I love the most are the battery life, adjustable brightness, and ease of use. Also handy: the subtle and semi-tactical red light, very handy when you don't want to blind everyone around you and preserve your own night vision. All for well under a hundred bucks. 5 stars from me.
