Personal alarm systems for mobile and home use

Having a personal alarm system for both mobile and home use gives me peace of mind, especially when I'm out walking the dog or home alone at night. The keychain device is small enough to clip onto my keys, and the home unit can be placed by the front door. One press sends a loud, piercing sound that scares off anyone who might be following me. It's a simple but effective tool that doesn't require a subscription or complicated setup, just instant security when I need it.
