High-performance, durable keyboard
The Corsair Gaming K70 RGB MK.2 (Cherry MX Silent Pink) is still going strong after 4 years of use. The typing quality is still excellent, and the RGB backlighting is as impressive as on day one.
The only minor problem after 4 years is that the space bar sometimes jams, but this is rare and hardly affects day-to-day use.
In short, a durable, high-performance keyboard, with a minor weakness over time, but still very pleasant to use.
