I recently bought a Cloud Defensive REIN Micro and so far have mixed feelings about it. I wanted something good that came as a complete kit that was easy to use. This is not what I found to be the case with the REIN MICRO. It did come as a complete kit but assembly is kind of a nightmare. The light control switch is about the most fiddley thing I've ever tried to assemble and even after watching several videos of how to route the cable through the cable management channels I've still not gotten it exactly right. No matter how I try to tuck the cable into the channels and tighten down the screws on the switch I can still pop it off with my fingers. I've got this thing tucked like a Target swim suit and it's still not secure. Also the switch body is polymer. For as much as this thing costs I expected aluminum. I've already managed to pinch the cable and it frayed the protective layer. It didn't get into the actual wire but it's still annoying. I already ordered a new switch assembly. Also the cable is ridiculously stiff and fights the whole time. I got it mounted and it is a nice concept and looks great and protects the wire well. If you can avoid pinching it during assembly. It's brighter than my Arisaka light but uses 18350 batteries which I'm not 100% crazy about but at least it's rechargeable and I don't have to search for batteries when needed. Overall it's nice but I don't feel it's worth the premium price. I would not feel comfortable running this light in a class or in a competition setting as I feel the switch will pop off at some point. I'm going to wait for my new switch assembly and try to remount it and hopefully not pinch it this time. But if it doesn't work out then I'll probably go back to my tried and proven Arisaka set up.
