I've had a Zipka for a few months. It's basically a Tikka without a head strap but uses a cord that reels into a windup module which sits behind your head. It's strength is the compact size: when reeled up, the Zipka is about the size of a jumbo egg, perfect for my car emergency kit.<br><br>Although the light is surprizingly comfortable for a headlight held around the head by a cord, it's only comfortable for short periods. I'm buying a second light, probably a Princton Tec Aurora which tilts, unlike the Tikka. <br><br>Neither light is really adequate for night hiking - LED's are still too dim, but they make good camp lights, and are great as utility lights for house repairs at night.
