After installing the MENGQI-CONTROL system for my small office, I can confidently say it delivers on its core promises—but with a few quirks. The fingerprint scanner impressed me with its accuracy, even recognizing my slightly sweaty post-workout fingers (unlike my phone’s sensor!). The color screen is crisp, and adding users via RFID cards or passwords was seamless.

The 600lbs magnetic lock feels *substantial*—my team literally hung on the door to test it, and it didn’t budge. However, the power dependency is a real concern (as noted by other reviewers). During a brief outage, our door swung open freely. I’d strongly recommend pairing this with a backup battery or mechanical lock for after-hours security.

Installation was mostly painless thanks to the included video guides, though the paper instructions might as well be hieroglyphics. Pro tip: Label your wires like a mad scientist—it saved me hours of frustration. The customer support deserves applause; they responded to my wiring question within an hour with a crystal-clear diagram.

Minor gripes? The included doorbell sounds like a dying robot (I replaced mine), and programming multiple entry methods per user could be more intuitive. But for under $200? This system outperforms pricier competitors I’ve tested. Just don’t skip the UPS battery backup—unless you enjoy surprise open-house days!
