What will you mostly use it for?
The RT75 wins only for gaming and travel, thanks to its magnetic rapid trigger technology, higher polling rate, and lighter compact build.

For mixed use, the IF99 offers far more versatility, while the RT75 is a specialized tool for competitive players who prioritize response speed over layout size.

Yunzii IF99 vs RT75: your questions
The RT75 is better for gaming because it uses Hall Effect magnetic switches with rapid trigger technology for faster key resets and dynamic keystrokes. It also offers adjustable actuation from 0.1 to 4.0 mm and supports up to 8000 Hz polling rate, whereas the IF99 is limited to 1000 Hz and uses standard linear switches.
Yes, the IF99 supports three connection modes: Bluetooth, 2.4 GHz wireless, and USB-C wired. It can connect to up to five devices and has a high-capacity 8000mAh battery, making it suitable for long wireless work sessions.
No, the RT75 is wired only according to the vendor specifications. It connects via USB-C and does not offer Bluetooth or 2.4 GHz wireless options, so it must remain plugged in at all times.
Hall Effect switches use magnetic sensors instead of physical contact to register keystrokes, resulting in greater durability and faster response times. The RT75's Outemu magnetic switches enable rapid trigger, adjustable actuation points, and dual-action keys for competitive gaming.
Yes, the IF99 includes a customizable LCD screen that can display the time, GIFs, photos, battery status, and connection mode. It can be personalized with your own images through the vendor's software.
The IF99 offers a better typing experience for office work due to its full 95% layout with a number pad, gasket mount design with multiple sound-dampening layers, and PBT Cherry profile keycaps. It also supports QMK and VIA for creating productivity-focused macros.
Yes, both the IF99 and RT75 are hot-swappable per the metadata. The IF99 supports 3-pin and 5-pin mechanical switches, while the RT75 is specifically designed for magnetic switches, so standard mechanical switches are not compatible.
The IF99 has a large 8000mAh battery, which supports extended wireless use via Bluetooth or 2.4 GHz. The RT75 has a 4000mAh battery, but since it is wired only, the battery is only relevant for its internal components and not for wireless operation.
The IF99 is easier to customize for advanced users because it supports QMK and VIA firmware, allowing key mapping, macro creation, and RGB adjustments from Windows or Mac. The RT75 uses a web-based software for customization but lacks the open-source flexibility of QMK/VIA.
No, the RT75 has a 75% layout with 82 keys and a knob, but no dedicated number pad. If you need a numpad for data entry, the IF99's 95% full-size layout with 95 keys is the better choice.
The RT75 is more portable, weighing 962g compared to the IF99's 1238.5g, and has a smaller footprint of 334mm width versus 385mm. Its compact size makes it easier to fit in a backpack or on a crowded desk.
Yes, both the IF99 and RT75 support Windows and Mac operating systems according to the metadata. The IF99 also includes Mac/Win support in its extra features, and the RT75's web software works on both platforms.
