Overall, it is a very interesting board with nice caps (the 2-part variety), and very interesting switches.
They are clicky, and sing-songy and very pleasant to type on. The keyfeel is light, a bit bouncy and smooth.

On the layout though, this does not seem to be the usual JIS layout which is why I have avoided using apostrophes since I cannot find the damned thing
