Cons

  • ✗ Macro and RGB programming software is Windows-only; Mac users lose remapping

  • ✗ South-facing LEDs underlight non-shine-through double-shot keycaps

Manufacturer description

The YUNZII B75 PRO brings a 75% layout with 82 keycaps and a multifunction knob to a desk footprint that still keeps function row, arrow keys, and number row intact. The pre-lubed Milk linear switches arrive ready to type on, and full-key hot-swap sockets accept both 3-pin and 5-pin switches when you want to change the feel later. Tri-mode connectivity covers Bluetooth, 2.4GHz wireless, and USB Type-C wired, backed by a 4000mAh battery so you are not recharging mid-session. South-facing LEDs drive more than 20 built-in backlight modes, and the knob doubles as a volume and lighting control…

Yes, it is compatible with Windows and macOS, and the tri-mode connection covers Bluetooth, 2.4GHz, and wired Type-C. Note that the programmable software for key remapping, macros, and RGB customization runs on Windows only.

Can I change the switches without soldering?

Yes. The B75 PRO uses full-key hot-swappable sockets, and the PCB accepts both 3-pin and 5-pin mechanical switches, so you can swap the stock pre-lubed Milk linears for tactile or other linear switches with a puller.

It has 82 keycaps. The layout retains the number row, function row, and arrow keys along with the knob, and drops the dedicated numeric keypad to save desk space.
