The Z11 features RGB lighting that can be controlled via the "Light" tab.
The E-Yooso Z11 offers impressive hardware for its price point, and while the software isn't as polished as Razer Synapse or Logitech G Hub, it is fully functional for customization. If you are a competitive gamer, downloading the driver is essential to fine-tune your DPI settings for that competitive edge.
Quick Tip: Always keep a backup of the extracted driver folder on your desktop in case you need to reinstall Windows
To understand the value of the Z11 software, you must look at the price bracket.
| Feature | E-Yooso Z11 | Redragon K552 | Corsair K55 | | :--- | :--- | :--- | :--- | | Software Availability | Difficult to find (Manual DL) | Easy (Official site) | Easy (iCUE) | | Onboard Memory | No | Yes | Yes | | Macro Support | Basic (Record only) | Advanced (Scripting) | Advanced (iCUE) | | RGB Customization | Per-key (Static only) | Per-key (Full) | Per-key (Full) | | Price Impact | Free | Free | Requires bloatware |
Verdict: The Z11 software is basic, but it is free and lightweight (uses only ~15MB of RAM). Unlike Corsair iCUE which uses 200MB+, the Z11 driver will not slow down your gaming.
E-Yooso does not have a unified software suite (like Logitech G Hub or Razer Synapse). The software varies depending on the specific PCB version of your Z11. There are generally two possibilities:
Check your keyboard: If pressing Fn + F1 through F12 changes lighting, you likely have onboard control only. If you need macro recording, you need the software.
A common Reddit thread asks: "Is the E-Yooso Z11 software a virus?"
Analysis: The software is not malware, but it is an unsigned driver. Major companies pay Microsoft for a digital signature certificate. E-Yooso, being a budget manufacturer, avoids this cost. Consequently, Windows warns you that the "Publisher is unknown."
Check the file hash: Before installing, upload the .exe file to VirusTotal. A clean E-Yooso driver should have 0/60 detections. If you see 1 or 2 detections labeled "Riskware," that is usually a false positive for software that modifies keyboard input (a necessary function for macros). If you see 10+ detections, delete the file immediately.
Perfect for MMOs or repetitive tasks.
Once you have downloaded the file, follow these steps to install the software correctly:
