Okay, so I installed this YBJ alarm system last week, and here's the tea ☕️.

The Good: Setup was stupid easy—no drilling, just slapped the host on the wall like a fridge magnet. The app (Tuya/Smart Life) actually works?? Got alerts when my cat tripped the motion sensor at 3AM (RIP sleep). Alexa integration is clutch for lazy arming.

The Glitchy: Random false alarms happened twice—once with NO open doors/windows. Had to silence it like a rogue iPhone alarm. Also, why no disarm code?? Burglars could just yeet the silence button 💀.

Pro Tip: Use the SIM card slot! When my WiFi died during a storm, 4G kept it running. Backup battery lasts exactly one workday (8hrs).

Verdict: 7/10. Works great... when it wants to. For $100-ish, I'll take those occasional false alarms over monthly fees any day.
