Take your personal safety seriously with the powerful Mace Ergo Stun Gun with LED. The impressive electrical arc and the loud snapping sound will often make a would-be assailant think twice about attacking. Depressing the stun button as a warning might be all you need to keep the would-be assailant from approaching. But, if it must be used, a shock of 1 second or less will cause pain and minor muscle contractions, 1 to 2 seconds will cause spasms and a dazed mental state, and 3 to 5 seconds will cause loss of balance and muscle control; do not continue to stun an assailant once you are able to escape to safety. The ergo stun gun can also be used as a 200 lumen flashlight.
