Third-party reviews

What we like about Cooler Master SK651 Wireless

  • Sleek and minimalist design with a high-quality brushed aluminum top plate
  • Low-profile Cherry MX switches provide a responsive and fast-actuating typing experience
  • Vibrant and highly customizable RGB backlighting with on-the-fly controls
  • Versatile connectivity options, supporting both Bluetooth wireless and USB-C wired modes
  • Slim, compact profile makes it portable and space-efficient on desks

What we don't like about Cooler Master SK651 Wireless

  • Flat, chiclet-style keycaps have very little spacing, leading to frequent typos and an 'irritating' typing feel for some
  • Proprietary stabilizers make it difficult or impossible to swap the keycaps for standard aftermarket sets
  • Bluetooth connectivity can occasionally experience input lag, which is not ideal for competitive gaming
  • The 'low-profile' height is still taller than some competitors (like the Keychron K1) due to the switch and PCB design

Verdict

The Cooler Master SK651 is a full-size (100%) wireless mechanical keyboard featuring a slim, minimalist design with a brushed aluminum top plate and low-profile Cherry MX Red linear switches. These switches offer a reduced 3.2mm total travel distance and 1.2mm actuation point, paired with flat, contoured keycaps for a chiclet-like aesthetic. It supports hybrid connectivity via Bluetooth 4.0 or a detachable USB Type-C cable and includes per-key RGB backlighting with 16.7 million colors, on-the-fly macro recording, and N-key rollover. Main pros include its premium build quality, versatile wireless functionality, and portable form factor for a full-sized board. However, notable cons include a relatively high profile despite its label, inconsistent typing comfort due to flat keycaps, and the lack of adjustable height feet or dedicated media keys.
