12 keychain gadgets worth carrying every day (and why they’re worth it)
The pocket-sized She’s Birdie is a personal safety alarm with a built-in, wildly loud siren. I’ve carried this on my keychain for almost 7 years, and it’s a great investment for college students, parents with small children, older adults, and more, but for about $30, I recommend everyone scoop one up.
When the top pin of the Birdie is pulled out, a 130db siren sounds and a strobe light flashes for up to 40 minutes. To put that in perspective, a 130db sound is equivalent to a jackhammer and nearly equal to the sound of a jet engine in the distance, according to the Hearing Health Foundation.
