78% recommend · 22% neutral · 0% don't
Owners praise
  • Impressively good sound straight out of the box, with owners calling it one of the best-sounding pre-builts they've used and noting a big improvement over previous boards
  • Strong value for the price, with owners saying it feels like it could cost far more (one mentioning it could pass for a 200€ CNC-aluminum board) and pointing to deals like a 10% discount code or ~$19 units as steals
  • Smooth, pleasant typing feel with solid build once assembled and good stock stabilizers
Owners complain about
  • Switch reliability problems that develop over months of use, including double-triggering or keys ceasing to register (reported anywhere from 5 weeks to 8 months in), plus switches needing regular internal cleaning and lubrication to stay reliable
  • Wired and wireless connectivity failures, including boards that won't connect at all out of the box, wireless dropping out or refusing to reconnect after weeks/months of normal use, and RGB not functioning correctly in wireless mode
  • RGB color gets washed out by tinted switch housings (e.g., cream yellow switches turning blue lighting whitish), with no real fix beyond swapping switch color or tweaking settings
