Redragon K681MG Pro vs UCAL K673 HE: your questions
The Redragon K681MG Pro offers tri-mode wireless connectivity, including Bluetooth, 2.4GHz RF, and a USB-C wired option. The UCAL K673 HE is a wired-only keyboard with a detachable USB-C cable.
The UCAL K673 HE uses UltraMag magnetic Hall effect switches. According to Redragon, these use a magnetic field for actuation, feature an anti-wobble dual-module floating structure, and support Rapid Trigger technology for adjustable actuation points between 0.1mm and 3.4mm.
The K681MG Pro has a hot-swappable PCB, allowing you to easily replace switches without soldering. The product listing for the UCAL K673 HE does not mention hot-swap capability, suggesting its Hall effect switches may not be user-replaceable in the same way.
The K681MG Pro is better suited for office work. Its wireless connectivity allows for a cleaner desk and easy device switching, it includes a volume/media control knob, and its lighter weight and aluminum case contribute to a more portable and premium feel for all-day use.
The UCAL K673 HE specifies an 8000 Hz (8K) hyper-polling rate. The product information for the Redragon K681MG Pro does not specify a polling rate, so it likely uses a standard polling rate like 1000 Hz.
Yes, both the Redragon K681MG Pro and the UCAL K673 HE feature RGB backlighting. The K681MG Pro's vendor description mentions 15 preset modes and 7 pure colors.
Both keyboards feature sound-dampening materials. The K681MG Pro lists a 5-layer filling including Poron and silicone pads. The K673 HE mentions a 5-layer noise dampening system with PO foam, IXPE switch foam, a PET sound pad, and a silicone bottom pad.
The UCAL K673 HE offers multi-platform driver support. Redragon states it has a standard Windows client and adds web-based driver support for accessing software features from other operating systems via a browser.
The K681MG Pro features an aluminum case, while the UCAL K673 HE has a plastic case. This contributes to the K681MG Pro's lighter weight (858g vs. 1240g) and typically more premium feel.
Rapid Trigger is a feature on the UCAL K673 HE that, when combined with its Hall effect switches, allows the actuation point to be dynamically adjusted. This lets a key reactivate without needing to be fully released, which can provide an advantage in fast-paced games by enabling quicker successive keystrokes.
The K681MG Pro listing mentions it comes with a switch/keycap puller and four extra switches. The K673 HE listing includes a keycap & switch puller and spare switches, but does not specify the quantity.
