I actually just got my Keks meter. I had forgotten I ordered it and got a DHL notification earlier this week that a package from Taiwan was being delivered, so it was a nice surprise when it arrived.
It's a nice, small meter, but it didn't fit well on its intended partner at first glance...my Barnack Leicas. Disappointed, I looked on the bottom and found that the shoe mount can be shifted to the right (from its default position in the center), giving the needed clearance! The case is nicely machined aluminum and the buttons have a nice click when pushed. It comes with two spare plastic shoe mounts, an Allen wrench for installing/removing them, and a charge cable. Very simple instructions are on a sticker on the underside of the lid of its box. First impressions are good and while I haven't film-tested it yet, it meters close to my smartphone app (within about half a stop).
