Summary
A 98-key tri-mode mechanical keyboard for shoppers who want gasket mount, hot-swap sockets and a control knob without spending much. Check which version you are buying: the anime-themed SE uses different switches and keycaps and costs more than the base board.
Strengths
- USB-C, 2.4 GHz and Bluetooth cover wired and wireless setups.
- Hot-swap sockets accept 3-pin and 5-pin switches, so swaps need no soldering.
- Gasket mount and five layers of dampening soften the typing sound.
- The 98-key layout keeps a number pad while cutting desk footprint.
- Owners report the 3000 mAh battery lasts for days between charges.
- A dedicated knob handles volume and backlight brightness.
Weaknesses
- The plastic chassis flexes; CGMagazine reports it can be twisted 20 degrees.
- Redragon’s software is clunky and buggy, and Redragon’s own guide warns it can brick a keyboard.
- Stock linear switches feel airy and membrane-like to one reviewer.
- RGB is dim behind non-transparent keycaps, especially in bright rooms.
- The USB-C port sits on the left side, which TechSpot calls awkward.
- The Right Shift is shortened and the arrow keys are shifted left.

Full research notes and sources
Battery, connectivity and the control knob
The keyboard connects over USB-C, 2.4 GHz wireless or Bluetooth 3.0 and 5.0 and switches between them. Owners say the 3000 mAh battery lasts for days between charges, and the manual references three Bluetooth slots. CGMagazine reports days of use with the default battery-saver settings, while noting that Redragon does not publish real-world figures with RGB on. The dedicated knob adjusts backlight brightness and media playback.
Build, switches and upgrades
Reviewers agree the plastic chassis is the weak point. CGMagazine reports the base board can be twisted 20 degrees and describes the stock linear switches as airy with the sticky feel of a membrane keyboard; it recommends swapping them. The hot-swap sockets take 3-pin and 5-pin switches, so any swap is solder-free, and the box includes 4 spare switches. TechSpot measured the SE switches at 40 g actuation force with a 2 mm actuation point and still called the typing experience the strongest part of the board.
Software and RGB
Redragon’s software handles RGB, macros, key remapping and debounce, but reviewers call it clunky and buggy. Tom’s Guide said bugs blocked customization and named the companion app poorly designed. Redragon’s own troubleshooting guide acknowledges the software can brick a keyboard. TechSpot found the RGB dim behind non-transparent legends, especially in a bright room. One owner on r/Redragon had RGB stop working and fixed it by resolving a software conflict, and another rates the board above a much pricier ROG keyboard.
Which model this is
This page covers the base K686 PRO in Blue Himmel with Red Linear switches and double-shot PBT keycaps. Redragon’s shop also sells a side-printed variant with Custom Leopard L switches and the K686 PRO SE anime version with Custom Hi-Fi Linear switches and DSA dye-sub PBT keycaps. The SE is a different board with different switches and keycaps, not a color swap. The US listing for the base model is ASIN B0CZ6SMBR4.
Is it worth it?
At the base model’s price the feature list is hard to match: gasket mount, hot-swap, PBT keycaps and a knob. Redragon’s official shop lists the base K686 PRO at $36.99 and the K686 PRO SE anime variant at $74.99. CGMagazine quoted an MSRP of $64.99 and a sale price of $42.74 in its August 2025 review. Tom’s Guide reviewed the SE at $74 in August 2024. TechSpot found the SE Anime on sale at $55 and the non-anime version at $47 in May 2025. The software limits and plastic construction are the tradeoffs at the low end, and the SE’s extra cost buys different switches and keycaps rather than a different keyboard.
