Mine arrived today-- in a box big enough for a football (I will recycle it).
I'm impressed with the lamp. I had seen them in stores but never laid hands on one. Good sealing, bright, easy to switch modes, and of course, light and compact. They had the sense to slot the battery door so you can use a battery to open it. The case is nicely made, but I doubt I'll use it. It would make a nice container for a survival or first aid kit.
The is the first small headlamp that I have seen that I would take as a primary light. With the Petzl and a micro light you can have all the lighting bases covered. This addition cuts my kit by 6oz (my old headlamp and the heavier back-up batteries) and saves some space too.
The light has a ten year guarantee, but the batteries' shelf life is more like five years and that is on a curve.
