附鑰匙圈個人警報器

I clipped this onto my keys and forgot about it until I needed it—the 110 dB alarm is genuinely jarring and cuts through noise instantly. It’s small enough to tuck into any pocket, which gives me peace of mind on evening walks.

Kept this on my bag strap during a late walk home and tested it once just to hear it — that 110 dB is no joke, easily loud enough to turn heads down the block. It's small and light enough that I forget it's there until I need it.

Clipped this to my keys the day it arrived and tested it in the hallway — that 110 dB is genuinely piercing, my ears were ringing for a minute. Nice that the key ring means it's always with me when I'm walking to my car at night.
