set of 4 personal alarms, loud 110 dB, with flashlight

Alarm transmitter and flashlight in one: The featherweight key fobsemit an extremely loud warning sound when you yank the chain.

110 decibels, as loud as a siren at a distance of 10 meters, will probably send any attacker running.

As soon as you return the pin on the chain to its position, the "siren" falls silent.

For more safety even in dark alleys: In addition, abright LED lights your way.
