Since the sensor doesn't fully show in the kinzu's shell, it lowered the LOD from about 3-4 cds to 1.5~2 cds, its very useable (the bottom of the sensor is blocked off in the same way that the tape trick blocks it)
and this was fairly easy, after ruining several mice attempting to make a nice one, this one was easy enough for me to handle.
the kana and kinzu have similar shell layouts, but the kana's is slightly bigger scaled, the scrollwheel of the kinzu fits fine in the kana pcb
I also stuffed some paper in the top right of the shell to gauge the click sensitivity
I'm happy to have a small 3090 mouse since my hands are so small
(kana v2 --> kinzu v1)
