Taiker Personal Alarm for Women, 10 Packs 140DB Emergency Self-Defense Security Alarm Keychain with LED Light for Women Kids and Elders (Colorful)

1 stopped working within a few days. Another stopped working right after that and the keychain broke off. The 1st one started working again, but how do I know it will work when it's needed?

I love them! I make safety keychains for ladies and I always order a lot at a time. I’ve never received a broken one! I have never been disappointed and nobody who has any of my keychains have ever told me their alarm never worked. I’ll continue to buy these alarms for my business!

I bought these for our church to send in Valentine's care boxes to our college students. They would also be useful for anyone on their own. I use it to deter other dogs when I'm walking mine since our neighborhood has a huge problem with loose animals. It's loud enough to get one's attention, but not deafening. It will startle an approaching animal but would not stop one that is determined to attack.

These are loud as a car alarm. I love them. The issue is. After about a month of wear on keys if the pin is pulled- it doesn’t work. The sound is crackled and barely recognizable. I’ve never had to pull mine and have only had it removed accidentally once. Briefly. It was pulled and did not work as hoped. My daughters completely became detached leaving the pin behind and she never knew so it never sounded.

Good object to have "HOWEVER," Battery does not last long, the screw is very small hard to find a screwdriver that will fit, You will have to test it every day to know when the battery is dead. while shopping for that size screwdriver the alarm was attached to the side of my pocketbook some how it got detached when getting out of the car never saw/ heard it fall because the battery was DEAD!!!!!!! it's a pack of 10. maybe they are disposable when the battery dies.I do not recommend them.
