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 RK61
Ranked #4 in Best Mechanical Keyboards Under $100
Royal Kludge RK61
2 sources$56.99as of Oct 16

The Royal Kludge RK61 offers a compact 61-key mechanical keyboard with Bluetooth connectivity and RGB backlighting, reviewed by Eds tech as ideal for both work and gaming. While praised for its build quality and backlighting, reviewers noted the lack of adjustable feet and cumbersome secondary function key combinations. YouTube reviewer Daniel from Beebom highlighted its quiet operation and NKRO support, though noted the switches lack pre-lubrication. It's recommended for users with limited desk space who don't need full-size keyboard features.

Strengths
  • — Compact 61-key design with 60% layout suitable for travel and small desks
  • — Bluetooth connectivity supporting up to 3 devices with blue LED backlighting
  • — Good build quality with minimal flex in the plastic chassis
Watch-outs
  • — Lacks adjustable rubber feet for ergonomic positioning
  • — Requires key combinations for secondary functions, less convenient than full-size keyboards

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 RK61

The Royal Kludge RK61's 61-key compact design and Bluetooth connectivity set it apart from the Redragon K552 Kumara, which lacks wireless capabilities. While the Epomaker TH80 Pro offers more advanced features like a color LCD screen, the RK61 provides a simpler, more straightforward experience with better build quality and less complexity than the Ajazz AK820.
