Okay, let’s talk about this MENGQI-CONTROL 4-door access system. I was *skeptical* at first—how could something this affordable handle 20,000 users and 100,000 records? But after three months of testing, I’m low-key obsessed.

The hardware feels solid—no flimsy plastic here. The metal power supply box handles 110-240V like a champ, and the TCP/IP connectivity? Chef’s kiss. Setup was smoother than expected thanks to their *actually useful* documentation (shocking, I know). Pro tip: Build a tabletop demo first to play with the software. Trust me.

Features that blew my mind: Time-based door rules (bye-bye, after-hours freeloaders), swipe-to-hold-open for deliveries, and power-failure-proof memory. My only gripe? No built-in remote monitoring (Xavi’s review nailed it—Mr. Cheng, take notes!).

Customer support deserves its own paragraph. WhatsApp responses at weird hours? Clear troubleshooting? Compared to big-name brands charging 10x more for less? *Mic drop.*

Final verdict: If you’re handy with wiring and want pro-grade control without the markup, this is your golden ticket. Just maybe reinforce those doors if ditching deadbolts—security first, folks!
