iSafe (Reviewed: Jan 2012) The iSafe fanny pack is always armed and ready for use. By quickly pulling down on the hidden draw strap you will immediately produce a mind numbing shrieking sound that is sure to draw attention, startle your attacker – gaining precious time to with an advantage over your attacker. iSafe is advertised as being the world’s loudest personal alarm system – containing two 125 decibel sirens and a high intensity LED strobe light. During a recent testing when we activated the unit – we awoke our entire office as well as probably the neighboring offices! Activation is simple – just pull the draw string down. You don’t have to worry about wondering when the batteries are low – a battery indicator light is built into the pack.
