I have the tactikka+. A decent headlamp, I guess. This fell out of my side pocket on a 4 day hike. It rained for two days. On my return i found it and picked it up thinking it would be dead, but it survived and still works perfectly. However, I really dislike the beam pattern on this though. The lens over the light has groove channels across it that diffuses the light in a more proximity type beam pattern (See attached photo). You can't focus this light for distance. Great for proximity lighting around camp, terribly terrible shitty-shit-shit for night hiking/navigating. The far superior Black Diamond ReVolt is my go-to lamp now. I keep my tactikka+ to lend to non-hiking friends who accompany me sometimes.
