Protect Yourself

What Self Defense Product should I buy? 

Firstly, it is important to buy something that is legal in your State.

Secondly, the self defense product you buy will depend on what you need it for. If you want something for example to protect yourself when walking or jogging, then a keychain self defense product would suit you best for example a pepper spray on a key chain or a personal safety alarm.

Attach it to your keys and bring it with you when walking, jogging, shopping-anywhere you're going, especially if alone. It may just save your life. 

If you need a self defense product for protection in your home, a stun gun is a good choice as well as the batons. You could also consider a door stopper so that you can lock yourself in a room should you ever need to.

For protection in your car, a flashlight baton is a popular choice.
