إنذار شخصي مع حلقة مفاتيح

I tested it in my hallway and the 110 dB siren is piercingly loud, exactly what I wanted for late-night walks to my car. The key ring attaches easily to my bag loop, so it's always within reach.

Pulled it out of my bag when I felt someone too close on the subway and the siren was loud enough that I swear the whole car turned. It's tiny, fits right on my keys, and the 110 dB blast is genuinely reassuring for late walks.

The key ring is solid enough that I clipped it to my bag loop and forgot it was there, which is exactly what I wanted. I did a quick test of the siren and my ears rang for a few seconds — that 110 dB is no joke, and it gives me real peace of mind walking home late.
