I guess I'll join this one if I'm lucky enough to see the link in time. This light is disappointing though. It doesn't bring anything new. No 14500 or 16340, even though a quality 14500 XM-L host is an untapped market. No right angle light. It even seems to lose some things. It doesn't look like it'll tailstand well, and the lanyard hole arrangement doesn't help. It doesn't have brass/copper rings at the end of the battery tube. Only one end of the battery tube is anodized. To me this light slots just below the S2. Maybe I'll get to find out.
It's not the permanent price though. The permanent should be about $11, imo. I'm not disappointed about it as a $5 light. It's disappointing that it's not worth a lot more. A high quality, well designed, 18650 right angle host would easily be worth $20 to me. I may sketch up some CAD designs as suggestions for any flashlight manufacturer.
It's kind of a lot of work, but it'll be worth it if it results in exactly what I've been longing for.
