The Niz L84 is en electro-capacitive keyboard released in late 2025. This keyboard was actually crowdfunded on Kickstarter and the campaign ended on 21 May 2025 with HK$ 60,216 (USD 7,742) raised.

The keyboard is available in dark grey and white.

• Cable - USD 195

The review unit I have is the wireless model without RGB and it's USD 235.

The silicone cover can make the typing sound even lower, barely audible, but it removes all tactility when typing so the typing experience isn't good.

Design

The keyboard looks like a low profile mechanical keyboard. Build quality feels solid. There's matte textured surface throughout, and rounded edges.

The OLED display shows program mode, connection type, battery life and keyboard layout. The display will deactivate with 5 or 10s (selectable) of inactivity.

The keyboard height is 1.9mm at the front and 2.4mm at the back.

The fold-out feet has two adjustable height.

An electro-capacitive keyboard is one that uses a hybrid mechanism that combines a rubber dome, spring and a capacitive sensor. It's almost like a membrane keyboard but has a softer feel.

The typing experience is soft. Actuation force is just 30g so it doesn't require much force to press down. Keys are sensitive and a slight press will activate the key.

Typing sound is low.

There's more key travel than normal membrane keyboard but noticeably less key travel than mechanical keyboard. I find it less tiring to type on the Niz keyboard and switching back to typing on a mechanical keyboard feels like doing more work as there's more key travel.

Typing on this keyboard feels like typing on a membrane keyboard but there's some tactile experience of a mechanical keyboard. It's probably a 8:2 ratio of membrance vs mechanical feel.

The Mac Function key is located at the top right area while the Windows Function key is at the lower left. I use Mac and the button to the left of the Delete key is a brightness reduction key, but there are the brightness up and down keys used by F1 and F2. So this keyboard has two keys that can reduce display brightness, and one (the top right) is unnecessary.

The space bar has less width than most keyboard. The right edge of this space bar aligns to the right edge of the M key, but should actually be below the middle of the , key. The result is sometimes my thumb would hit the R-Alt key instead.

For Mac users the R-Ctrl key will become a R-Opt. I need to mention this because some keyboards will give you a L-Opt instead, or a R-Ctrl.

The right area under keys 7-8-9 can be used as a numpad using a keyboard shortcut.

The four rubber feet on the back has good grip on the table. The fold-out feet only have plastic padding for feet.

The hole for the USB-C charging port is small making it very difficult to use other USB-C cables, so make sure you do not lose the USB charging cable that's included.

Power button's located at the top left and has to be pressed to wake the keyboard. The keyboard will not wake by pressing normal keys.

There are no switch or toggles for switching connection or keyboard layout. Switching between connection requires using keyboard shortcut. Switching keyboard layout is done automatically as the keyboard detects the OS, and this is quite convenient.

The left side of the keyboard can actually be used as a mousepad too, and to activate mousepad mode requires using a keyboard shortcut.

Software

There's a Windows-only software that can be used to customise the keys. I did not test the software though so I can't say much about the software functionality.

The keyboard can only be paired to two devices using Bluetooth by default, and you'll need the software to add the third.

The actuation point can be adjusted using the software, from 0.6mm to 2.6mm in 0.1mm steps.

Conclusion

This keyboard looks good and is well made. One key feature is how quiet this keyboard is when typing as it barely makes any sound. The second key feature is the low actuation force together with less key travel means typing is less tiring, and this can be good for people who need to type for long periods of time. These would be the two key features that could be worth paying for because otherwise you can get other keyboards at much lower prices.

There are several downsides or limitations but none are deal breakers. The keyboard layout will take some time to get used to, especially for the spacebar that is less wide. For Mac users, the Mac Function key is at the top right.
