Great lamp in many respects, easy to use light... but the headband is a complete nightmare. They have made it so so complicated that you can't get it tight enough, comfy or to sit in the middle. The modular system is handy, but doesn't seem robust, the battery comes off easily and the light on to the strap does not seem a positive connection. Time will tell...
Ref Fresh Air Junkie... swift delivery, but seems I have a retuned item, the box has been opened, and the packaging had been damaged, clearly not an unopened item. I would have returned but I was in need of the light for a weekend trip.
