Review on 🚨 Evershop USB Rechargeable Personal Alarm - 130dB Emergency Self Defense Keychain Siren for Women, Kids & Elderly with SOS Alert Panic Button, LED Flashlight - Safety Devices by Brian Trujillo

Great personal alarm clock. Noisy. Best of all, it's rechargeable so you don't have to change batteries, it's flat so you can put it in your pocket (unlike teardrops), it's backlit, the key ring also VERY easy to attach to your Attach keychain because it's a spring clip. In addition, they are easy to turn on, but not so easy to accidentally turn on. I have one for myself and one for each of my daughters. Again, it's easy to remove the keychain. My 20 year old daughter carries it in her bag when she rides her bike and when she's done she clips it back to her keychain.
