Now you can buy Streetwise stun guns and feel safer that ever before. If you want to defend yourself from a safe distance and do not want to carry along a bulky stun baton, the Streetwise 700,000 volts Expandable Stun Baton is the perfect solution.  It extends from 12 1/2 inches to 21 inches with the touch of a button. In addition to the powerful 700,000 volt stun gun it also features an ear piercing 130 decibel alarm.  As a bright electric current pulsates up and down the top 12 inches, it creates an intimidating electrical sound that can often stop a would-be attacker in his tracks.  If the sight and sound of the electric current and the personal alarm are not enough to stop him, a jolt of 700,000 volts certainly will!  The stun baton uses 4 CR123A three volt lithium batteries (not included).
