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

Redragon EISA K686 Pro vs Keychron V6: your questions

Only the Redragon EISA K686 Pro offers wireless connectivity. According to its product page, it supports Bluetooth and 2.4 GHz wireless modes in addition to a wired USB-C connection. The Keychron V6 is a wired-only keyboard.

Yes, the Keychron V6 supports extensive reprogramming. It is compatible with the open-source QMK firmware and the VIA configurator, allowing for deep key remapping, macro creation, and layer customization directly through software.

Yes, the Redragon K686 Pro features a 96% layout. This design incorporates a number pad into a compact form factor by removing some of the spacing between keys, making it smaller than a standard full-size keyboard while retaining the numpad.

The Keychron V6 is available with a choice of Keychron K Pro switches. The vendor listing shows options for Red (linear), Blue (clicky), and Brown (tactile) switches. The K Pro switches are described as factory pre-lubed for smoothness.

They use different mounting styles which affect feel. The Redragon K686 Pro uses a gasket mount with sound-absorbing pads, which its description says provides a softer, more cushioned typing experience. The Keychron V6 uses a tray mount with a steel plate, which typically offers a firmer, more direct feedback.

Both keyboards offer PBT keycaps. The Redragon K686 Pro uses PBT keycaps. The Keychron V6 uses double-shot PBT keycaps in an OSA profile, which the manufacturer states are oil-resistant and prevent legends from fading.

Yes, both keyboards are hot-swappable. The Redragon K686 Pro listing states its sockets support both 3-pin and 5-pin switches. The Keychron V6 product page also confirms its PCB supports hot-swapping for 3-pin and 5-pin MX-style switches.

The Redragon K686 Pro is a 96% layout keyboard, measuring 90 x 430 x 90 mm. The Keychron V6 is a full-size 100% layout keyboard, measuring 19 x 141 x 448 mm. The V6 is larger, heavier, and includes a full navigation cluster and more spacing between keys.

Yes, both keyboards list Mac support. The Redragon K686 Pro has a side button for switching between Windows and Mac layouts. The Keychron V6 includes a system toggle and an additional set of keycaps specifically for macOS compatibility.

Based on the listings, the Redragon K686 Pro package includes a detachable USB-C cable, a 2.4 GHz nano receiver, a keycap and switch puller, four spare switches, and a user manual. The Keychron V6 listing for the fully assembled version includes keycaps, switches, and a Type-C cable with an adapter.

Yes, both the Redragon EISA K686 Pro and the Keychron V6 feature south-facing RGB LEDs. This orientation helps prevent interference with Cherry-profile keycaps and often provides better lighting from the typist's perspective.

The Redragon K686 Pro may be more approachable due to its plug-and-play wireless functionality and included accessories like spare switches. The Keychron V6 is excellent for beginners interested in learning customization, but its wired-only nature and focus on programmability might appeal more to those ready to dive into firmware tweaking.
