Yunzii RT75 PRO Review

A year ago I reviewed the Yunzii RT75 which was a good value Hall effect keyboard and now there’s Yunzii RT75 PRO version which has come out. It’s starting price is $79.99 and it comes with Outemu red magnetic switches. Biggest changes? It’s wireless, top-mounted and has 8000 Hz polling rate.

YUNZII RT75 PRO is available in two colors, black and pink one and I got the black one. It feels pretty solid, I like that it has a knob which is a standard in gaming keyboards, but it’s useful.

There’s plenty of things in the box: additional keycaps, cable, keycap and switch puller, two extra switches, extra keycaps, dongle, strap and a manual.

Latency

RT75 PRO had three connection modes: wired, Bluetooth and 2.4GHz using a dongle. Scan rate is 128k and polling rate is 8000 Hz. And the latency is pretty good. I tested it with OSLTT. Wired single key latency is 0.65 ms and via 2.4G it’s 1.01 ms. It’s an average score from 10 tests. Very good performance, only a few magnetic switch keyboards have better wired latency and at below 1ms it’s negligible.

Software

Software is basic QMK web app and it’s not that great. It works, but the UI is pretty bad and I had some issues when setting up actuation points. It worked after a bit of testing though. You can set all the usual gaming stuff like Snap Tap, Rapid Trigger, adjustable actuation points, Toggle Switch, ModTap etc.

You can access the web app by going to https://qmk.top. There are some good customability options that aren’t available in every Rapid Trigger keyboard such as:

• RTStab (RT Stable Increase Algorithm, 25%-100%) – When RT Stab is turned on, the algorithm intervenes to enhance the stability of the bottom of the switch. The higher the intervention percentage, the stronger the stability, and the delay will also increase.
• Anti-Accidental Trigger Mode – This feature prevents accidental triggering due to desktop shaking or switch tolerances, which may cause a 0.1 mm travel discrepancy. When enabled, the algorithm optimizes the bottom key trigger to compensate for the travel discrepancy and improve keyboard stability.

There are macro options, combo keys, and function mappings, allowing you to assign actions such as a mouse click to any keyboard key.

You can also change polling rate (125-8000Hz) and set sleep timer for 2.4G RGB and Bluetooth.

The RGB is quite nice, the keycaps aren’t transcluscent (aside from Tab, Caps Locl, Shift and Enter), but keycaps are decent and the white print on them is quite visible with RGB on. An alternative option to get this with see-through keycaps would be nice though.

Outemu Magnetic Red (Sunset) Switches

The switches are from Outemu and they are red magnetic switches. They are probably a second brand aside from Gateron that makes pretty decent magnetic switches and these are fine. No noticable wobble and they sound better than most magnetic switches.

Outemu Magnetic Red Switch Specs

• 0.1 mm to 3 mm customizable trigger points
• total travel 3.5±1 mm
• force travel 45±5 gf
• initial force 30 gf
• end force 55 gf

The keyboard is also compatible with other magnetic switches from KS-20 lineup such as Gateron Magnetic Jade/Jade Pro/Jade Gaming, TCC Magneto/KOM/POM and other Outemu magnetic switches. And in the software you can choose from these switches to make the changes more accurate.

One weird thing I encountered is that the Escape key cannot be easily removed or replaced. Keycap puller can’t get through and you need a knife or something else in order to extract it out.

Build quality is really decent for this price point. The case is made out of plastic, but that is to be expected, you can’t really get an aluminium case keyboard at this price. It’s top mounted.

The sound is really good, especially considering that most magnetic switch keyboards are pretty medicore in that aspect.

Would I use YUNZII RT75 PRO as my daily driver keyboard? Yes, I would, it’s really good value and I haven’t had any major issues while using it for about 2 weeks now.

You can purchase Yunzii RT75 PRO from their official store. Review unit was provided free of charge, but that didn’t impact my opinion in the slighest.
