Thanks for posting a review of the KBP V60 Type R Polestar.
I have had good experiences with my KBP V60 keyboards, although I have not yet tried the Polestar. I am not much of a fan of LED special effects, although there are times when I would find backlighting useful. It is important to note that KBP produces a "standard" Type R as well as a Polestar Type R, which has the special lighting effects.
The KBP V60 Type R boards are indeed fully programmable, which is a big deal. This makes the Type R more versatile than the Pok3r, which is quite versatile, but not completely programmable. On a standard 60% board, I like to reprogram it with a HHKB layout and use the R_Ctrl as Fn. With the Pok3r, there appears to be no straightforward way to remap the R_Ctrl, but this is easily done with the V60 Type R.
Although I like the V60 boards, and especially the Type R, Cherry mx and clones are my least favorite types of switch. KBP also produces V60 boards with Matias and Datacomp Alps switches, but these are not nearly as nice as some varieties of Alps that unfortunately are found only in vintage boards.
