This Bolt Siren is our best seller because it has an added protection of sounding an alarm so it doubles as a personal alarm.  It is 1.6 Microcoulombs of stun power with 100 lumens of light.  This means it has more than enough power to take down an attacker.
It has a disabling strap and when the strap is removed, it sounds a very loud siren sound and also disables the stun gun so it cannot be used against you.  
This Bolt Siren Stun Gun measures 4.4" x 1.57" x 0.98"
The Bolt Siren Stun Gun is available in black and purple.
