5075B

78%of 18 owners recommend

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
