Ok, Spaߟ aside .... the effectiveness of defense sprays offered here is quite ok.
But what I just want to mention absolutely: Not everyone is such a spray regularly.
Should the situation occur and the spray should be activated, the user is usually excited, panicked or confused.
The result is that he in the handling and uncertain - which is even more important - is not fail!
The content of 20 ml is enough for just one probably. two Sprühstöߟe but then also have to "sit".
For inexperienced almost impossible !!! What happens if the attacker is missed, do not need to be explained further ...
My recommendation therefore quite clear: at least 60 ml capacity even if the can is something gröߟer, it still fits into any pocket. Auߟerdem have gröߟeren doses a finger securing and schlieߟen incorrect operation in the form of, for example, can hold out in the wrong direction. Furthermore, it is in groߟen can be able to operate them with your thumb, what a much better accuracy means and greatly expanded the range of motion of the wrist. Try it once with a Deoflasche and actuates this once with the index finger and then with your thumb. The difference is quickly realized.
Always remember that you also should not save here. It's your health that want to protect their cheap ...... is never cheap here!
