FAQ for portable alarm systems buyers

1. Can I use the same keychain multiple times?

Yes, you can. Most devices are designed to be used several times.

2. The technical specifications indicate decibels, so how do you know how loud the device really is?

Certainly, the sound is measured in a completely different way, as opposed to distance. A person, in the daytime, can hear sounds with a volume of 10-15 dB or higher.

For comparison, people talk with a volume of 40-45 dB, a human cry reaches 85 dB, and the sound of an airplane engine at the start – 130 dB. This pain threshold has a depressing effect on the new human system and a destructive one on the auditory system.

3. Why choose the alarm button from the list of self-defense tools, and not a stun gun?

Let’s think logically. The disadvantages of stun guns include the fact that people have different health, different hearts, and the use of this device may cause sad consequences.

Moreover, if the attacker is wearing very tight clothing, the stun gun may simply not work. Finally, the alarm button can be activated faster than pulling a shocker out of your pocket. Sometimes, we only have a few seconds.

4. Probably it is better to use pepper spray?

If a jet of pepper spray hits the face, the attacker will be blinded for a few seconds and lose the ability to make decisions and act. The desire to continue the attack will be significantly reduced.

However, practice shows that in a stressful situation, the can is often dropped, they do not have time to spray it, or they themselves become victims of its contents
