A flexible connection setup, not a fully documented gaming package

The Redragon K671KS combines three connection modes with hot-swappable switches, programmable controls and adjustable RGB. This review covers the Deep Black, 3 Mode configuration with the red switches identified in the listing. It is a specification-based assessment of the supplied retailer information, not a hands-on evaluation of its typing feel, wireless responsiveness or build quality.

The strongest reason to consider this model is flexibility: it could serve a gaming PC while also accommodating other devices, and its controls are advertised as customizable. The main reservation is incomplete documentation. Dimensions, key count, battery life and detailed switch compatibility are absent, so several practical buying decisions remain unresolved despite the broad feature list.

Listed specifications and the gaps that matter

Connectivity is the attraction; switching details need checking

Redragon lists USB-C wired operation, Bluetooth 3.0/5.0 and 2.4GHz wireless, with support for up to five devices. A physical switch sits on the back. For someone dividing time between a gaming computer and a separate work or tablet setup, that combination offers more connection choices than a single-interface keyboard.

However, the listing does not explain how the five-device allowance is divided between connection modes or precisely how individual devices are selected. Treat that figure as an advertised device-support limit, not proof of five Bluetooth pairing slots or simultaneous input to five systems. The rear switch also deserves consideration if the keyboard will sit directly against a monitor stand or another desk accessory: leave room to reach it.

There are no supplied latency measurements, polling rates or wireless stability results. Accordingly, neither wireless mode can be endorsed here for timing-sensitive gaming on measured performance grounds. Battery capacity and runtime are also unspecified, leaving the charging routine unclear. USB-C wired operation is the documented option for buyers who prefer a wired connection, but the evidence does not describe charging behavior during use.

Remapping could simplify your controls, subject to software support

The K671KS is advertised with key remapping, shortcut assignment and macro editing, including combining multiple functions onto a single key. Those options matter if your preferred controls differ from a game’s defaults or if you want repeated desktop tasks placed on more convenient keys. The listing also describes individual-key RGB adjustment, which could help visually separate groups of bindings.

What it does not establish is equally important: there is no description of onboard profile storage, dedicated macro keys or whether customization remains active after moving to another computer. The product title mentions PC, tablet and Mac use, but that does not establish that the configuration software works on all those platforms. Before buying for a mixed-device setup, verify software compatibility and whether saved mappings follow the keyboard.

For gaming, think of macros as an optional configuration tool rather than an automatic competitive advantage. Check the rules of the games you play before assigning multi-action sequences. Simple remapping may be the more relevant feature if your goal is comfortable access to existing controls rather than automation.

Replaceable switches without a clear compatibility map

The supplied feature text identifies red switches and advertises hot-swappable replacements. It also lists eight spare switches and two red keycaps. Spare switches are a useful inclusion for replacement needs, while the swap capability gives buyers a potential route to changing the keyboard’s feel without replacing the entire board.

The evidence does not specify the switch manufacturer, actuation force, travel or socket pin compatibility. Do not assume that a replacement switch advertised for another Redragon keyboard will fit this one. Confirm the K671KS socket requirements before ordering a custom switch set; the broad invitation to customize is not a detailed compatibility guarantee.

Double-injection PBT keycaps and a metal panel are the stated material features. A metal panel does not establish an all-metal enclosure, and neither material description tells us how the assembled keyboard sounds. There is no documented mounting structure or internal damping here, so claims about a cushioned, quiet or especially solid typing experience would go beyond the evidence.

Desk fit remains the biggest pre-purchase check

The supplied listing gives no dimensions, weight or key count. That prevents a reliable assessment of mouse clearance, portability or whether the layout includes every key you need. On a gaming desk, this is more consequential than the cosmetic finish: verify the physical footprint and layout before planning around a large mouse area or a narrow keyboard tray.

Lighting is better documented, with 16 presets, speed adjustment and five brightness levels advertised. Those controls provide some scope to reduce visual distraction, although the listing supplies no evidence about lighting uniformity or visibility in different room conditions.

Verdict: promising flexibility, conditional recommendation

The K671KS makes the most sense for buyers who value multiple connection options, remapping and replaceable switches. Its included spares and adjustable lighting round out that specification set. Buyers with strict desk-space limits, platform-specific customization needs or wireless performance requirements should first confirm the missing details. The listing supports a versatile feature proposition, but not a confident judgment about responsiveness, comfort or endurance.
