Just got my Zipka! Really like it a lot. I'm not super experienced with headlights so maybe I'm just easily impressed, but it's super lightweight, easy to operate, and a nice beam.
HualicopterI love the zipka. I keep one in my backpack and just ordered 2 more for my car and toolbox. I don't like it for anything active. Tikka is better for that (or I use a Black Diamond Spot). But it's great for having around.
