KBP uses low-quality switches, likely reject switches of another manufacturer, another reject switch user is massdrop
KBP also can't apply Cherry stabs well, their application sucks beyond imagination, clicky switches don't click, tactile switches are almost stiff linears
Anyway, when I got my KBP V60, I was shocked, I de-soldered the stabilised switches, clipped and lubed the stabs, replaced the faulty switch (a clear switch at that ...)
Filled the case with coins to add heft (great mod by the way, there are a lot of empty spaces in the case)
After these modifications, I fell in love with mine, didn't even replace the stock keycaps, I think they fit the keyboard extremely well
I've also noticed that the PCB supports a lot of other layouts, so it's like a hidden gem, a custom firmware could enable other alternative layouts, but I'm not sure how the screw situation is, there's probably something in between the pcb and the plate that the screws went into, so it's far from a standard 60%
I still keep my KBP V60 in my library, we spent like a month together, but bonded well through external circumstances
I increased my daily income tenfold while using the KBP V60, so it kind of left the impression that the keyboard was lucky, after I switched to an infinity keyboard, I suffered severe losses on the business end, and my income roughly returned to previous levels
As a small warning, the keyboard doesn't handle other keycaps well, D/SA's rub to something on the stabilised keys - so I think KBP V60 is a great keyboard to just buy, fix, and use with the standard keycaps and standard layout (imo, only the Shift+Esc->~ is missing from the default layout, Control+J->~ wasn't ideal)
