I used BFO-9000 PCB which allows to break off some rows/columns. So, it's actually a split keyboard with two 6x7 pieces and low profile switches. I like the narrow width and number of available keys. Keycaps are black & white, but what I miss is different shapes of keycaps for easier tactile orientation. As a workaround I added keycaps with tactile nubs to some extra keys (enter, backspace, alt & tab). It helps, but it's not as good as different shapes would be.
