After installing the MENGQI-CONTROL board in my office, I was blown away by its value. For under $1k, this 4-door controller replaces systems costing 5-20x more. The hardware is rock-solid – it flawlessly handles my HID card readers and exit buttons without a single hiccup in weeks of use.

The real MVP? The support team. When I struggled with programming (admittedly not my forte), they responded within hours – even sending annotated screenshots! Their PDF manuals need serious translation upgrades though. Figuring out advanced features like time-based access felt like solving a puzzle with hidden key combos.

Network setup has quirks: The mobile app requires devices to be on the same subnet, which is a dealbreaker for enterprises with complex networks. But for small businesses? It's perfect. The software looks dated but gets the job done – just don't expect cloud-based modern interfaces.

Pro tip: Buy their enclosure bundle if starting fresh. My only regret was wrestling an old cabinet to fit this board when their complete kit would've saved hours. For DIYers tired of predatory security company pricing, this is your rebel solution.
