I received my KWS-X1 from Aliexpress today (seller: ThinkingLeader, 17 CAD).
It came with firware version 1.0.5
It's a bit buggy. (resets itself often)

Upgrading the firmware to v1.0.5V solved the problem!

V1.0.5
- Enhanced PPS Support (20mV voltage steps, max 21V, current accuracy ±0.8%)
- Faster and More Stable Negotiation
- Improved PDO interpretation
- Enhanced measurement accuracy (ADC 5kHz, improved transient capture)
- Improved usability (1.8-second startup, automatic backlight dimming)
- Bug fixes (memory leaks, display errors, calibration retention)
- Added factory reset
