I recently got my hands on the ZZRUI Upgraded Door Stopper Security Alarm, and let me tell you, this little gadget is a game-changer for anyone who values security—whether you're traveling solo or just want extra peace of mind at home.

The Good: First off, the alarm is LOUD. Like, fire-alarm loud. At 120dB, it’s impossible to ignore. I tested it in my apartment, and my neighbors definitely heard it (sorry, guys!). The adjustable sensitivity levels are a nice touch—I kept mine on high for maximum security. It’s also super portable and lightweight, making it perfect for tossing in your luggage. The battery life impressed me; it lasted weeks without needing a replacement.

The Bad: While the alarm is effective, the build feels a bit flimsy. If someone pushes the door too hard, the stopper can slide, which defeats the purpose. Also, the alarm doesn’t have volume control—once it’s on, it’s ON. So if you’re in a noisy environment or have thin walls, this might be overkill.

Real-World Use: I took this on a solo trip to a sketchy Airbnb, and it was a lifesaver. Placing it under the door at night gave me that extra layer of security. Plus, the non-skid base works great as a regular door stopper when you don’t need the alarm feature.

Final Verdict: For under $20, this is a solid investment for travelers or anyone wanting added security at home. Just don’t expect it to physically stop an intruder—it’s all about deterrence with that ear-piercing siren!
