Let me start by saying this little door alarm packs a serious punch! The 120dB alarm is LOUD - like, 'scare-the-neighbors-and-the-dog' loud. I installed it on my back door and accidentally set it off while taking out the trash. My heart nearly jumped out of my chest!

The ABS construction feels surprisingly sturdy for such a lightweight device. It's survived several months of daily use without any issues... unlike one reviewer whose unit fell off and stopped working (pro tip: make sure it's securely attached!).

Now here's where it gets interesting - the modding potential! As a weekend paranormal enthusiast, I was fascinated by reviews about converting these into ghost detectors. After some simple modifications (adding an LED indicator and volume control), I've been using mine during investigations. The sensitivity is perfect for detecting unexpected movements in supposedly empty rooms.

The installation couldn't be simpler - just hang it on any door knob. No wires, no complicated setup. Though I will say the included instructions could be more detailed about proper placement to prevent false alarms.

While primarily designed for security, this versatile little device has become my go-to for both home protection and... well, let's just say 'unconventional' uses. Whether you're looking to deter burglars or detect the supernatural, this alarm delivers surprising value for its price point.
