After testing the MENGQI-CONTROL system for 3 months across multiple properties, I'm blown away by its professional-grade features at a fraction of commercial system costs. The metal power supply box feels industrial-strength, and the TCP/IP connectivity works flawlessly with my existing network.

What I love: The software is surprisingly intuitive - setting up time-based access rules for different departments took me just 15 minutes. The 20,000-user capacity handled our office building's needs easily, and power failure protection gives peace of mind. Installation was smoother than expected thanks to their detailed video guides.

Real-world performance: In our converted Victorian house office, the RFID readers respond instantly (tested with HID cards). The auto-close feature prevents tailgating, while continuous swipe override is perfect for moving days. I particularly appreciate being able to check entry logs remotely through the software.

Room for improvement: While the controller supports advanced features, first-time users might find the wiring diagrams slightly overwhelming. Adding remote monitoring (as suggested by other users) would make this system perfect. Also wish it included basic door hardware in the core package.

Final verdict: For under $900 in parts (including mag locks), this outperforms systems costing 10x more. The responsive support (special shoutout to Mr. Cheng!) makes it ideal for DIYers tackling multi-door installations. Just be prepared to spend a weekend learning the software's full capabilities - it's more powerful than it looks!
