I have a Nextorch Z1 and really love it. I have a review in the Review forum, the link is available in my sig. Overall, the machining and build is great. Finish is very consistent. The tailswitch is a tactical one (momentary push, constant twist) which I like as it has the reliability of a twistie while providing momentary. Output is very bright for a 1cell (I'd estimate about 35-40lumens) on a primary and around 55lumens on a rechargable. Battery tube is wide and able to fit rechargables with room to spare. The beam is very nice with a tight hotspot, no donut hole at all even when close to the wall, and great throw. Tint on mine is very white. I know this isn't the Z3, but it's the smaller version of it. I wouldn't be surprised if the Z3 outputed 60lumens. A very nice light overall.
