Personal Defense Alarm
This is light weight and loud, so it will get the job done.
Two things to consider on this product:
- It has an on-off button so you don’t accidentally activate it, and
- Battery life may be an issue if you keep it on
Plus, it’s plastic, so no one is going to think this is an expensive piece of jewelry.
So, if you are the meticulous type or like fancy jewelry, you may want to go with a more practical alarm.
Still, this device is pretty cute.
