Summary

A 75% tri-mode mechanical keyboard with a TFT screen, control knob, gasket mount, and hot-swappable linear switches. Check the software before you buy: the driver is Windows-only, and multiple owners report instability.

Strengths

  • Gasket mount and factory linear switches produce a sound owners call creamy and thocky.
  • The screen and knob combination is a distinctive feature at this price.
  • Hot-swappable switches let you change the feel without soldering.
  • Up to 5 paired Bluetooth devices for users with multiple systems.
  • PBT double-shot keycaps and a switch/keycap puller are in the box.
  • South-facing RGB with 19 lighting effects and a music-sync mode.

Weaknesses

  • Windows-only driver software is a recurring pain point: multiple Reddit users report instability and trouble uploading GIFs.
  • Bluetooth polling is 125 Hz, noticeably lower than the 1000 Hz of wired and 2.4GHz modes.
  • One owner reports battery life of only 3-4 days in 2.4GHz mode with RGB on.
  • Stock keycaps feel unpleasant to at least one owner, who considered replacing them.
  • The 80-key versus 84-key discrepancy between AULA’s own pages is unexplained.
  • GIF upload requires renaming files to “0” and placing them in a specific folder.

Typing feel and sound

The gasket mount and factory-lubed linear switches are the keyboard’s strongest asset. Owners on Reddit and YouTube describe the sound as creamy and thocky, and the typing feel is considered strong for the price. The PBT double-shot keycaps are durable, though at least one owner found the texture unpleasant and considered replacing them. The package includes a keycap and switch puller plus two extra switches, so experimenting with the feel is straightforward.

Screen and software

The 1.14-inch TFT screen and metal knob are the main differentiators from other 75% boards in this price range. The screen shows time, battery status, and custom GIFs, while the knob controls volume and screen navigation (hold Fn + Wheel for 2 seconds to switch modes). The catch is the software. The driver is Windows-only and requires wired mode, so Mac users cannot customize lighting, macros, or screen content. Multiple Reddit users report instability and difficulty uploading GIFs; the process requires renaming files to “0” and placing them in a specific folder.

Battery life and wireless performance

The 4000 mAh battery is rated at about 30 hours with backlight on and 80 hours with it off. One owner reports approximately 3-4 days of use in 2.4GHz mode with RGB on, which is broadly consistent with the claim under typical usage but not a controlled test. Bluetooth polling is 125 Hz, which may be noticeable for gaming compared to the 1000 Hz available in wired and 2.4GHz modes. The keyboard supports up to 5 paired Bluetooth devices, useful for users with multiple systems.

Value

At $65-75, the S75 Pro offers a compelling feature set: tri-mode connectivity, gasket mount, hot-swappable switches, TFT screen, knob, and PBT keycaps at a budget price. The lack of professional test data and software reliability concerns are acceptable tradeoffs at this price. Above that range, the value proposition weakens as more established alternatives with better software ecosystems become available. Compare with the Epomaker G84 and other 75% tri-mode boards in this range.
