Let me start by saying this little gadget has been a game-changer for my elderly mom. The setup was straightforward—plug in the receiver, connect it to WiFi via the Tuya app (yes, it only works with 2.4GHz, despite one reviewer’s accidental 5GHz success story!), and pair the wearable buttons. The wristband is comfy and waterproof, which is great for showers.

The GOOD:
- Reliable alerts: When Mom pressed the button from her garden (about 800ft away), my phone screamed with a custom ringtone I set—no subscription needed!
- Multi-user sharing: My siblings all get alerts simultaneously, which eased our caregiver anxiety.
- No battery hassle: The receiver stays plugged in, and the buttons last months on a single charge.

The NOT-SO-GOOD:
- App glitches: Like others, I struggled with SMS authorization codes failing after the first contact. Tuya’s interface feels like it was designed in 2010.
- Volume control lies: That ‘adjustable alarm volume’ in the manual? Myth. The receiver’s siren could wake the dead—I had to muffle it with tape!
- Mystery hole: Both units arrived with an unexplained ‘on/off’ labeled cavity (no actual switch). Weird but harmless.

Real-world test: When Mom fell last week, the alert reached me at work instantly—but did startle my coworkers! For $5/month-free peace of mind (unlike some deceptive alternatives), I’d recommend it despite its quirks. Just don’t expect polished software or whisper-quiet alarms!
