Yunzii’s IF99 mechanical keyboard is a rare blend of performance, aesthetics, and personalization.

Build Quality & Design

From the moment you lift the IF99, you can tell it’s crafted for enthusiasts. At 1.23kg, it’s no featherweight—but the heft adds to the premium feel.

The gasket-mounted structure gives it a soft, cushioned typing experience. PBT keycaps are double-shot for durability and pre-lubed stabilizers reduce rattling out of the box.

A magnetic aluminum badge smartly conceals the wireless receiver—a clever touch.

Customization & Software

If customization is your thing, the IF99 excels. The hot-swappable PCB supports both 3-pin and 5-pin mechanical switches, making it perfect for switch modding without soldering. QMK/VIA compatibility allows for deep-layer remapping, macros, and RGB control across four programmable layers.

But there’s a catch—while VIA and QMK handle key functions and lighting well, the LCD screen customization is tied to proprietary software. This means open-source fans may find it limiting.

Real-World Use

In daily use, the IF99 delivers one of the smoothest and most comfortable typing experiences in its class. The combination of pre-lubed stabilizers, gasket-mounted construction, and quality keycaps makes every keystroke a joy. It’s built for long hours—whether you’re editing spreadsheets, coding, or gaming.

However, it lacks a volume knob, and while you can remap volume keys, it’s less tactile. Portability is also limited due to its size and weight, and there’s no carrying case included.

Pros and Cons

Final Verdict

The Yunzii IF99 is more than a keyboard—it’s a platform for personalization and performance. With its vibrant LCD screen, enthusiast-grade build quality, and deep customization options via QMK/VIA, it’s one of the most complete keyboards in the sub-$150 bracket.

While it stumbles slightly with proprietary software for screen control and the lack of a volume knob, those minor setbacks are overshadowed by the wealth of features on offer.
