Plus there will be more light modes, and it's almost certainly much closer to its actual stated brightness than that Chinese junk.

I don't think so, the junk light is $17 including 4-cell battery and charger, and the extra 6-cell pack that I like is $12. I bought a flood lens for one for $5. As opposed to $66 for the Cygolite. So the Cygolite might be a better or much better light, but it's 3x the cost.
