The Redragon K673 GB is a 75% wireless mechanical keyboard with 81 keys, a gasket-mounted plate, five layers of sound dampening, hot-swap sockets and pre-lubed linear switches. It connects by USB-C cable, Bluetooth or a 2.4GHz receiver. If you want a compact, quieter-sounding keyboard that you can use with a gaming PC and a laptop without buying a premium custom board, it covers the features that matter on paper. The trade-off is that Redragon publishes very little about polling rate, battery life and software, so some questions remain open.
This article is based on Redragon’s official product page, the Amazon.in listing and the official pages of the alternatives, all checked on 17 October 2026. We have not tested the keyboard, and nothing below is a hands-on impression.
Quick verdict
- Best for: gamers and typists who want a smaller board with a function row, a softer and more muted sound, and the option to change switches later
- Skip if: you need a numpad, want confirmed wireless polling-rate and battery-life figures, or need official macOS support and key mapping
- Key strengths: three connection modes, gasket mount, five-layer dampening, 3-pin and 5-pin hot-swap sockets, PBT keycaps, a volume and brightness knob, a 4000mAh battery (official page)
- Key limitations: no published polling rate or battery life, the software is not named or described, Bluetooth is listed as BT 3.0/5.0 with no multi-device pairing details, and the weight differs between the official page and the Amazon.in listing

The affiliate link in this article points to the Concrete Jungle colourway with Custom Mint Mambo linear switches. Redragon also sells other colourways, so do not assume a different colour is the same listing. Check the current price of the Redragon K673 GB on Amazon.in.
The name confusion: K673 GB, K673 PRO and UCAL
Redragon is not consistent with naming. The Amazon.in listing calls this keyboard the K673 GB. Redragon’s own online store sells what appears to be the same board as the “UCAL K673 PRO”, and its box-contents list names a “Redragon K673 PRO GB Keyboard”. The features, foam stack, switch name and knob described on both pages match. This matters when you search for reviews, manuals or software: try all three names, and match the switch (Mint Mambo) and colour to the Amazon listing before you trust a review of “the K673”.
Gasket mount and five dampening layers: why they change the sound
Many traditional keyboards screw the plate directly to the case. Every keystroke then travels into the plastic shell, which can produce a hollow, ringing sound and a harsh feel when a key bottoms out. A gasket mount suspends the plate between soft silicone strips, so it can flex slightly. The result is usually a softer, more even feel across the board and less case noise.
Redragon adds five sound-dampening materials on top of the gasket: a 3.5mm PO foam, IXPE foam under the switches, a PET sound pad, bottom socket foam and a silicone bottom pad. These fill empty space inside the case and soak up vibration. Redragon says this “significantly” reduces hollow noise. That is a plausible result of the design, but we found no independent sound test to confirm it. If you share a room or join voice chat often, the dampening is one of the better reasons to pick this board over an older, undampened design.
Mint Mambo linear switches and hot-swap sockets
The K673 GB ships with Redragon’s Custom Mint Mambo switches, which are linear. A linear switch has no tactile bump and no click: the key goes straight down with steady resistance. That suits fast repeated presses in games and gives quiet, smooth typing. Redragon describes them as thick-lubed from the factory. It does not publish actuation force or travel distance, so you cannot compare their weight with other linear switches on paper.
The board has hot-swap sockets that accept both 3-pin and 5-pin switches. You can pull a switch out with the included tool and press in a new one without soldering. This is a strong long-term feature: if the linear switches do not suit you, you can try tactile or heavier switches later, and a single faulty switch is easy to replace. The Amazon.in listing includes spare switches in the box, and Redragon’s store lists four spares.
- Pull switches straight up, using the tool’s clips on the top and bottom of the switch housing.
- Check that the pins on a new switch are straight before pressing it in, because bent pins are a common hot-swap mistake.
- Press new switches in with the keyboard on a flat surface, and test each key afterwards.
- Note the switch type before buying replacements, so you know whether you are fitting 3-pin or 5-pin switches.
Three connection modes, and which one to use
Here is how to think about the three modes.
- USB-C wired: the most predictable mode for competitive gaming.
- 2.4GHz wireless: uses the nano receiver and is generally the wireless option gamers prefer, because these dongle links are usually more responsive than Bluetooth. Redragon does not publish the polling rate for any mode.
- Bluetooth: listed as “BT 3.0/5.0”. Useful for a tablet, phone or work laptop without spare USB ports. Bluetooth on keyboards generally adds more delay than a dongle, so keep it for typing.
Redragon does not say how many Bluetooth devices the keyboard can remember, how long the 4000mAh battery lasts, or how long it takes to charge. Keeping RGB lighting on full brightness usually shortens battery life on any wireless keyboard. If battery life matters to you, lower the brightness with the knob when you are working wirelessly.
The 81-key layout and the knob
A 75% layout keeps the letters, numbers, arrows and a full function row, and drops the numpad and most of the navigation cluster. Redragon says the K673 GB keeps the length of a 65% board while adding the F-key row, so you do not need Fn combinations for F1 to F12. For gaming, the shorter board leaves more room for wide mouse movements. For office work, you lose the numpad, which matters if you enter many numbers in spreadsheets or accounting software.
The knob in the corner controls backlight brightness and media: volume, play/pause and track switching. If you are setting up a work desk as well as a gaming corner, our work-from-home desk setup guide covers keyboards, mice and monitors for Indian buyers.
What Redragon does not tell you
- Polling rate: not stated on the official page or the Amazon.in listing.
- Battery life and charging time: not stated. Only the 4000mAh capacity is given, on the official page.
- Operating systems: the official page does not list Windows or macOS support. The Amazon.in listing says it is compatible with PCs, laptops, tablets and gaming consoles. There is no mention of macOS key mapping.
- Software: the official page says software is supported and has a download section, but does not name the software or say what it controls.
- Weight: 1.2 kg on Redragon’s page against 800 g on the Amazon.in listing. The truth may be either.
Who should buy it, and who should not
Buy it if you game on a PC, want a compact wireless board that sounds and feels more refined than a basic plate-mounted keyboard, and like the idea of swapping switches later. The function row and knob make it practical for everyday typing as well.
Skip it if you work with numbers all day and need a numpad, want clear wireless specs before buying, or use a Mac as your main computer. Without official macOS key mapping, modifier keys may need remapping.
Alternatives worth comparing
- Keychron V1 Max: also a 75% gasket-mounted board with a knob, 4000mAh battery and 3-pin or 5-pin hot-swap. Keychron publishes far more detail: up to 190 hours of battery, 1000Hz polling over 2.4GHz and wired, Bluetooth 5.1 for up to three devices, double-shot PBT keycaps, QMK firmware with VIA remapping, and Windows, macOS and Linux support.
- Keychron K2: a 75% board with 84 keys, Bluetooth 5.1 for up to three devices and wired USB-C. It has a 4000mAh battery rated for up to 240 hours with the backlight off, hot-swap support and official macOS support. It has no 2.4GHz dongle mode and uses ABS keycaps.
- A wired-only gaming keyboard: if your keyboard never leaves your desk, skipping wireless avoids battery and pairing concerns altogether.
Before you order: a short checklist
- Colour and switch: confirm the listing shows the Concrete Jungle colourway and Custom Mint Mambo linear switch, as covered here.
- Box contents: the Amazon.in listing mentions a keycap/switch puller, spare switches and a USB cable. Redragon’s store also lists a nano receiver, a manual and a sticker. Make sure the 2.4GHz receiver is in the box when you unpack it, because you need it for 2.4GHz wireless mode.
- Warranty: the listing describes a 1-year manufacturing warranty where you send the keyboard to a service centre. Keep the invoice and the box.
- Layout: it is a US QWERTY layout, so check that your keycap legends and any language settings are what you expect.
- Mac users: plan to remap keys with your operating system’s settings if needed.
Once you have confirmed the variant, see the Redragon K673 GB (Concrete Jungle, Mint Mambo linear) on Amazon.in.
Frequently asked questions
Is the Redragon K673 GB hot-swappable?
Yes. Redragon says its sockets accept nearly all 3-pin and 5-pin switches, so you can change switches without soldering.
What switches does the K673 GB use?
It uses Redragon’s Custom Mint Mambo linear switches, which are lubed at the factory. Redragon does not publish their actuation force.
Does it have a numpad?
No. It is a 75% layout with 81 keys. It keeps the arrow keys and a full F1 to F12 row but has no numpad.
What is the battery capacity and battery life?
The official page lists a 4000mAh battery. Neither Redragon nor the Amazon.in listing states how many hours it lasts.
Is the K673 GB the same as the UCAL K673 PRO?
Redragon’s own store sells the UCAL K673 PRO with the same feature list and calls it the “K673 PRO GB” in the box contents, so they appear to be the same keyboard sold under different names.
Final thoughts
On paper, the Redragon K673 GB brings features once limited to enthusiast keyboards to a mainstream gaming brand: gasket mount, heavy dampening, hot-swap sockets, PBT keycaps and three connection modes. Its weak point is missing information: polling rate, battery life, software and Mac support are all unclear. If those gaps do not worry you, check the current price of the Redragon K673 GB on Amazon.in.
