After weeks of testing the MENGQI-CONTROL system across my property, I'm blown away by its professional features at a DIY price point. The metal power supply box gives instant confidence in build quality.

The 0.2s card swipe recognition is snappy - no awkward waiting at doors. I particularly love the infrared exit buttons which blend perfectly with US electrical boxes (no ugly protrusions!). Weatherproof readers survived my intentional hose test with zero issues.

Software setup was surprisingly intuitive. Creating time-based access rules for my cleaning staff felt like programming a smart thermostat. The USB card reader for enrollment is GENIUS - no tedious manual entry. Though as some reviewers noted, documentation could be better organized.

Pro Tip: The TCP/IP connectivity allows remote management that rivals systems costing 5x more. I regularly check entry logs from my phone when traveling. Battery backup (sold separately) is absolutely worth adding for power outages.

Minor gripe: The trial software expiration issue mentioned by one user seems isolated - my full version activated flawlessly. When I did have questions, Chen's support team resolved them in under 30 minutes via screen sharing.

For under $500, this system outperforms the $3,000 professional install I was quoted. It's transformed how I manage access across multiple buildings while saving thousands. Just ordered two more units!
