There's another thread on RCG on the HK 1.6m. My bet is whatever factory was making the (discontinued) BJ Craft Monolog 70 just took the tooling for it and started making it for HK with a different color scheme. I don't know how these Chinese factories work and if anyone enforces licensing over there. Being that HK sells both genuine iMax B6 chargers and copy iMax B6 chargers in the same eStore, I get the impression that some of these Chinese companies just manufacture / sell whatever they can get their hands on and get away with.
