Best for

What will you mostly use it for?

The Keychron V6 is the clear choice for users who need a primary, full-sized keyboard for gaming, programming, or deep customization. Its comprehensive layout and modding features make it a versatile centerpiece. The Cidoo V21 excels as a secondary device for travel or content creation, where its wireless portability and dedicated numpad function are key. For office use, both are competent, with the decision leaning on preference for a wireless peripheral versus an all-in-one wired board.

For gaming

Pick the Keychron V6

  • The Keychron V6 has a specified 1000 Hz polling rate for potentially lower latency.
  • Its full layout includes all standard gaming keys without relying on a separate device.
  • The tray mount with a steel plate may provide a more consistent typing feel for gaming.

Praise
“Great keyboard. Love using it. Two quibbles: Logo is backwards on Windows key Wish Caps Lock lit up—the LED underneath isn’t enough to indicate when Caps Lock is engaged.”
Andy D.Verified buyer· via Keychron
Critique
“I have never used a keyboard where every time you just as much barely graze a key' it registers. This is horrible, you pretty much have to perfectly press the keys dead center, otherwise, it will press surrounding keys as well.”

FAQ

Cidoo V21 vs Keychron V6: your questions

No, the Keychron V6 is a wired-only keyboard. It connects via a USB Type-C cable, which is included with the board along with a Type-A to Type-C adapter.

Yes, the Cidoo V21 listing states it has Mac/Win support. Its programmability through VIA software allows for key remapping to suit either operating system.

Mount styles affect feel differently. The Cidoo V21 uses a gasket mount with a PC plate and Poron foam, which may offer a softer, more cushioned typing experience. The Keychron V6 uses a tray mount with a steel plate, which typically provides a firmer, more direct feedback.

The Keychron V6 is sold in two variants. The fully assembled version includes Keychron K Pro switches and double-shot PBT keycaps. A barebones version is also available, which does not include switches or keycaps.

The Cidoo V21 has a 1000mAh battery. The manufacturer does not provide an estimated battery life in hours, as it depends on usage patterns and RGB lighting settings.

Yes, both keyboards support reprogramming. The Cidoo V21 is programmable via VIA. The Keychron V6 supports programming through both the open-source QMK firmware and VIA.

No, according to the Keychron product description, the double-shot PBT keycaps on the V6 are not shine-through. The south-facing RGB LEDs are designed to illuminate the board from a typist's angle.

The Cidoo V21 package includes the numpad, a keycap and switch puller, a 2.4G wireless dongle, a 1.6m Type-C braided cable, and a user manual.

The Keychron V6 has features relevant for gaming, including a 1000 Hz polling rate and N-key rollover. Its full layout and hot-swappable PCB also allow gamers to install preferred switches for gaming performance.

The Keychron V6 is likely more beginner-friendly for full keyboard modding. It is hot-swappable, supports many switch types, and is available as a barebones kit. The Cidoo V21 is also moddable but is limited by its small numpad form factor.

Yes, both the Cidoo V21 and the Keychron V6 feature south-facing RGB LEDs. This orientation helps prevent interference with Cherry-profile keycaps and can provide better lighting from a typist's perspective.
