After testing the MENGQI-CONTROL system for 6 weeks across my office building, I'm blown away by its value. The metal power supply box feels industrial-grade, and the weatherproof readers survived a thunderstorm without hiccups. Swiping cards feels satisfyingly quick - that <0.2s read speed is no joke.

The real MVP? The TCP/IP connectivity. I remotely unlocked doors for deliveries while sipping coffee at home. Creating time-based access rules (like restricting warehouse entry after 6PM) took literal minutes in their software. Pro tip: Their USB card reader saves hours when registering 50+ employee fobs.

Installation was smoother than expected - reused my existing door magnets and wired everything following their video guides. Though be warned: The PDF manual reads like scattered puzzle pieces. I had to cross-reference three documents just to find the default admin password (it's '123456' btw).

Tech support deserves a standing ovation. When I botched the strike plate wiring at 11PM, Chen from support did a screenshare session within 20 minutes (yes, they work crazy hours). Their responsiveness almost makes up for the janky software trial situation - one user reported license issues, so maybe confirm software details before purchase.

For under $500, getting enterprise-level features like SQL database integration and 100,000 log capacity is insane. My only gripe? The exit buttons feel slightly cheap compared to the rugged readers. But watching my old $3,000 Keri system gather dust in storage? Priceless.
