What Makes a Good Lightweight Self Defense Keychain
I have spent over 30 years helping families find protection that fits their real lives, and a keychain device only works if you will actually carry it. Here is what I encourage every customer to look for:
- Small enough to attach to keys without adding bulk to your pocket or bag
- A grip you can hold securely, even with shaky or sweaty hands
- Rechargeable power so it is always ready, not buried in a drawer waiting on batteries
- An added feature, like a flashlight, that earns its place on your keyring every day
