Focus-Adjustable Cree Q3 3-Mode White LED Headlamp (3 x AAA)

Pros: A lot of light for a little cost: it looks durable
Hard-built (except for the union with the headstrap)

Cons: It uses a lot of battery: with rechargeable batteries it lasts a little bit more, but it's normal as it gives a very powerful light. If you need durability better get a set of batteries.
I don't like the screw for opening the battery box, it's not very useful.
The part of the casing that joins with the strap looks thin and fragile, if you are'nt careful it won't last. It can be repaired or reforced with some epoxy resin and a metal piece reforcement.

Other: Good for it's price. I've a lot of headlamps and this is the most powerful ant the less expensive, but next time I'll get a one with a more durable and rechargeable battery so i need to use a lot of times in long nights (trekking and camp) but it's a good option for having it in the car or at home.
