The Corsair K70 Core RGB is a wired full-size mechanical keyboard with pre-lubed Corsair MLX Red linear switches, a volume dial and per-key RGB lighting. RTINGS called it an excellent gaming keyboard, citing outstanding latency, good overall build quality and light switches with short pre-travel, though it found the mostly plastic body and ABS keycaps somewhat cheap feeling. PCMag found its internal foam made it noticeably quieter than boards without foam, but judged it a feature or two away from being easy to recommend, with no hot-swappable switches and a gummy feel to some keys. It suits gamers who want a low-latency full-size wired board; anyone who wants wireless, a compact layout or switch swapping should look elsewhere.

Strengths
  • — RTINGS measured outstanding latency, roughly on par with pricier K70 models
  • — Pre-lubed Corsair MLX Red linear switches are light with short pre-travel
  • — Internal foam makes typing quieter than on boards without any foam
Watch-outs
  • — Mostly plastic build and ABS keycaps feel somewhat cheap
  • — Wired only, with no hot-swappable switch sockets
  • — Linear switches only, and PCMag found some keys felt gummy
Royal Kludge RK84
Ranked #7 in Best Mechanical Keyboards Under $100
Royal Kludge RK84
2 sources$56.99as of Oct 15

The Royal Kludge RK84 is a budget-friendly 75% mechanical keyboard featuring hot-swappable switches and multiple connectivity options.

  • — Hot-swappable switches in different flavors
  • — USB passthrough with dual USB ports (USB-C and two USB-A)
  • — Solid build quality with magnetic feet included
Watch-outs

How they stack up

Corsair K70 Core RGB

The Corsair K70 Core RGB is a wired-only full-size board, while the Keychron K2 Wireless and Epomaker TH80 Pro are 75% layouts that also connect wirelessly. It keeps the number pad that the tenkeyless Redragon K552 Kumara leaves off, and it uses linear switches where the K552 ships with clicky blue ones.

Royal Kludge RK84

The Royal Kludge RK84's hot-swappable switches and dual USB ports distinguish it from the Redragon K552 Kumara, which lacks these features. Compared to the Epomaker TH80 Pro, it doesn't offer a color LCD screen or integrated battery, but it provides more connectivity options than the Ajazz AK820, which lacks USB passthrough.
