How the alternatives differ
Redragon 60% Hot-Swap Mechanical Keyboard
The Redragon K617 drops the wireless features and OLED display found on the COSTOM board. You get a strictly wired 60% layout instead of a 75% form factor. This means you lose the dedicated arrow keys and function row, saving significant desk space. It keeps the hot-swap capability, so you can still change switches without soldering. The trade-off is the absence of Bluetooth or 2.4GHz connectivity. You should pick this if you prioritize a smaller footprint and do not need wireless freedom. It is a practical choice for gamers who want a compact, wired hot-swap keyboard without extra features.
SOLAKAKA A75 Compact Wireless Keyboard
The SOLAKAKA A75 matches the 75% layout and includes a volume knob similar to the COSTOM model. It adds gasket mounting for a softer typing feel compared to the COSTOM’s triple absorption layers. Connectivity is tri-mode, covering wired, Bluetooth, and 2.4GHz wireless options. It also supports hot-swappable switches. The main difference is the aesthetic, featuring a gradient blue-purple color scheme rather than a solid grey. You should choose this if you want a similar compact layout with a gasket mount structure. It offers comparable media controls and switch customization for gamers needing a versatile wireless setup.
AJAZZ 75% Mechanical Keyboard with TFT Screen
The AJAZZ AK820 Pro features a 75% layout with a TFT screen and volume knob, mirroring the COSTOM’s premium controls. It uses gasket mounting, which differs from the COSTOM’s internal foam layers. This board supports hot-swappable switches and offers Bluetooth connectivity. The dimensions are slightly more compact in width and length than the COSTOM model. You should pick this if you value a gasket mount construction and a dedicated display screen. It provides similar media control functionality but with a different mounting style and potentially longer battery life. It fits enthusiasts who want premium build features in a compact form factor.
RK Royal Kludge 98% Wireless Mechanical Keyboard
The RK Royal Kludge R98 Pro expands significantly to a 98% layout, adding a numpad and more keys. It retains the volume knob and hot-swap support found on the COSTOM board. The gasket mount style is similar to other alternatives but differs from the COSTOM’s specific foam design. It uses linear switches and includes PBT keycaps. You should choose this if you need a larger layout for data entry or extensive macro usage. It sacrifices the compactness of the 75% form factor for a full-sized experience. This option suits users who want wireless connectivity and physical media controls without needing a desktop app for configuration.
Kisnt Full-Size Wireless Mechanical Keyboard
The Kisnt KN104 is a full-size keyboard with a numpad, contrasting sharply with the COSTOM’s compact 75% design. It includes a volume knob and hot-swap capability, maintaining some feature overlap. The board uses linear switches and offers Bluetooth connectivity. Its dimensions are much larger, prioritizing a complete typing surface over desk space saving. You should pick this if you require a numpad for numerical data entry. It gives up the portability and compactness of the COSTOM model for a traditional full-size layout. This is ideal for users who prioritize numeric keypad functionality and multi-device wireless switching in a retro beige design.
RK Royal Kludge M75 Wireless Gasket Keyboard
The RK Royal Kludge M75 returns to a 75% layout, matching the COSTOM’s form factor. It features gasket mounting and an OLED display with knob controls, similar to the COSTOM’s interface. Hot-swap support is included for switch customization. The board is wireless, offering comparable connectivity options. The main difference is the gasket mount construction versus the COSTOM’s internal foam layers. You should choose this if you prefer a gasket mount feel in a compact layout. It offers versatile wireless performance with OLED controls. This option fits buyers who value compact layouts and hot-swappable switches over full-size designs, providing a similar control scheme with a different internal structure.

Frequently asked questions
Which retro keyboard has a gasket mount for better typing feel?
The SOLAKAKA A75 and AJAZZ AK820 Pro both feature gasket mounting. This design isolates the PCB from the case, reducing harsh vibrations. You get a softer, more flexible typing experience compared to traditional mounted boards. Both models also include hot-swap sockets for easy switch customization.
Can I use these keyboards with a Mac computer?
Yes, the SOLAKAKA A75 and AJAZZ AK820 Pro explicitly support Mac operating systems. They also work with Windows. This dual compatibility allows you to switch between devices without needing separate hardware. Check the keycap legends to ensure the command and option keys align with your setup.
Which option is best for users who need a number pad?
The Kisnt KN104 is the only full-size option in this list. It includes a dedicated numeric keypad for data entry and calculations. The Redragon K617 is too small, offering only 60% layout. If you need those extra keys, the Kisnt model provides the necessary space and layout.
Do these keyboards support wireless connectivity?
Most options here are wireless. The COSTOM M87 Pro, SOLAKAKA A75, AJAZZ AK820 Pro, RK R98 Pro, Kisnt KN104, and RK M75 all offer wireless connections. The Redragon K617 is wired only. Wireless models typically support Bluetooth for multi-device pairing, letting you switch between your computer and tablet easily.
Which keyboard offers the longest battery life?
The RK Royal Kludge R98 Pro is highlighted for its massive battery capacity. This large battery supports its 98% layout and wireless features for extended periods. While exact hours are not listed, the emphasis on battery size suggests it outlasts smaller boards like the 60% Redragon K617, which requires no charging.
Are hot-swappable switches available on all these models?
Yes, every keyboard in this list supports hot-swappable switches. This feature lets you pull out switches and insert new ones without soldering. You can customize the typing feel by changing switches. This applies to the compact 60% Redragon K617 up to the full-size Kisnt KN104.
Which keyboard includes an OLED or TFT screen?
The COSTOM M87 Pro features an OLED screen, and the AJAZZ AK820 Pro includes a TFT display. These screens show system status, battery levels, or custom images. The RK M75 also offers OLED controls. This visual feedback helps you monitor keyboard status without looking at your computer monitor.
What is the difference between 60% and 75% layouts?
A 60% layout, like the Redragon K617, removes the function row, arrow keys, and navigation cluster. It saves desk space but requires function key combinations. A 75% layout, such as the COSTOM M87 Pro or SOLAKAKA A75, retains the function row and arrow keys. This offers a balance between compactness and usability.
