Is this actually PBT or coated ABS?

PBT, confirmed by the matte surface texture and the slight chalky sound when tapped against a fingernail. Dye-sub requires PBT's higher heat tolerance; the process physically dyes the plastic rather than printing on top. No coating to wear through.

How does XDA compare to Cherry for daily typing?

Cherry profile has sculpted rows that cradle fingertips at different angles, reducing extension on the top row and compression on the bottom. XDA's flat plane demands more consistent wrist positioning—some typists report reduced strain from the uniform motion, others find themselves hunting for home row more often. The 350g set weight keeps the board from skating, but doesn't add the heft of thick PBT SA sets.

What keyboards does this actually fit?

The 128-key coverage spans 61-key (60%), 64/68-key (65%), 75%, 84-key (75% compact), 87-key (TKL), 96-key (1800 compact), 104-key, and 108-key full-size. Not included: support for Alice/split layouts, 40% boards, or non-standard bottom rows like Logitech's G Pro series. Verify your spacebar length (6.25u standard, 7u alternate included) and right-side modifier widths before ordering.
