The MMORPG.com review highlights the Cooler Master SK621 as an ultra-compact 60% keyboard featuring Cherry MX Low Profile Red switches, brushed aluminum, and dual-mode Bluetooth 4.0/USB-C connectivity, which provides an excellent, portable, and customizable RGB gaming experience. However, the, compact layout requires a steep learning curve due to missing keys and non-standard keycap spacing, making it less ideal for heavy typing and prone to accidental keystrokes.

The Cooler Master SK621 is a compact, 60% hybrid mechanical keyboard priced at $119.99 that utilizes low-profile Cherry MX Red linear switches. Designed for portable gaming, it features a minimalist design with a brushed aluminium top plate, a reflective brass bezel, dynamic per-key RGB backlighting, and a detachable braided USB-C cable for wired use or charging. Its standout positive attributes include an incredibly sturdy build quality with zero frame flex, a remarkably quiet typing experience compared to standard mechanical keyboards, and highly responsive gameplay owing to the shorter 3.2mm key travel and 1.2mm actuation distance. Furthermore, it excels in portability—fitting easily into an included velvet travel bag—and offers exceptional customisation, allowing users to record macros, reassign keys, and mix RGB layouts directly via "On-the-Fly" shortcut keys or through Cooler Master’s robust Portal desktop software. Despite its premium construction, the reviewer notes several distinct drawbacks that prevent it from being a universal fit. The primary issue stems from the flat, laptop-style chiclet keycaps which sit exceptionally close together with only a 3mm gutter between them, leading to a consistently high typo...

The MacSources review of the Cooler Master SK621 White Wireless Mechanical Keyboard highlights it as an aesthetically striking, ultra-compact "special edition" hybrid keyboard that can be used via Bluetooth 4.0 or a detachable braided USB-C cable. Built with a premium brushed aluminum top plate, it features Cherry MX Low Profile RGB switches that offer a soft, smooth tactile feel and a nearly silent operation compared to standard mechanical keyboards.

The Cooler Master SK621 Bluetooth Keyboard is reviewed as a highly compact, ultra-portable 60% tenkeyless mechanical keyboard tailored for gamers and writers on the go. Built with a premium gunmetal aluminum and plastic chassis, it balances lightweight portability with structural rigidity, fitting easily alongside a tablet inside a standard shoulder bag.

The bit-tech.net review evaluates the Cooler Master SK621, a niche £140 ($120) mechanical gaming keyboard built around a highly compact 60% form factor, wireless Bluetooth connectivity, per-key RGB lighting, and low-profile Cherry MX Red switches. The review praises its sturdy yet lightweight build quality, featuring a premium brushed aluminium top-plate, and its excellent space efficiency which makes it ideal for travel. It includes useful "on-the-fly" physical shortcuts mapped to keycap symbols and an included travel pouch. Additionally, its battery life is outstanding, promising four to five months of usage with the RGB lighting turned off. However, the reviewer highlights several prominent drawbacks, most notably the flat, chiclet-style keycaps. Because the keycaps lack proper contouring and are spaced closely together along a flat plane, they frequently cause typos and accidental double-key presses, requiring a long adjustment period. Connectivity is another mixed bag; while it successfully pairs with multiple devices using three onboard Bluetooth 4.0 channels, the reviewer experienced severe latency and dropouts when pairing it with certain laptops. Other cons include its high price tag, a lack of adjustable typing angles...

KitGuru The review underscores several notable pros and cons concerning the daily usability of the device. Among its positive attributes, the pros include its sturdy, "downright sexy" low-profile design, excellent portability, and smooth low-profile Cherry MX switches that enhance the gaming experience. Its hybrid wireless/wired configuration, on-the-fly macro creation, and exceptional battery longevity when the power-hungry RGB illumination is disabled are also heavily praised.

Additionally, the compact nature means the keyboard lacks retractable feet to adjust typing angles, it produces the characteristically louder "clickety-clack" acoustics of a mechanical keyboard, and battery life is reduced to just a couple of hours if gaming with full RGB animations active.
