Pros & Cons

Pros

  • ✓ 100 PBT keycaps across 10 colors, 10 each of black, white, red, orange, yellow, green, cyan, blue, p
  • ✓ PBT plastic resists shine and heat better than the ABS caps most boards ship with
  • ✓ Blank R4 faces let you flag WASD, macro, or nav keys by color instead of legend
  • ✓ Fits Cherry MX, Gateron, Kailh and other MX-stem switches
  • ✓ Keycap puller included, so no separate tool purchase to swap caps

Cons

  • ✗ Every cap is 1U R4 only, so no spacebar, shift, enter or other modifier sizes
  • ✗ R4 row profile on every key means a flat, non-sculpted feel across the board
  • ✗ Blank faces mean no legends, a real learning curve if you are not a touch typist
  • ✗ Only 10 caps per color, limiting large single-color blocks on a full-size board
