THE MOST POWERFUL STUN GUN I COULD FIND. 2,700,000 VOLTS OF TAKE DOWN POWER. Now with a built in led flashlight. bigger contact studs that stick out. A built in plug so NO more batteries - just plug it in to a 110 Volt outlet and let charge for 24 hours before you use it. Dont abuse it and it will last. Don't keep your finger on the button to show off to your friends for more than a second or 2 unless your zapping someone. For personal protection use only. This is not a toy and should not be used on politicians, even though we really, really want to. Slightly bigger than the 1.5 million I had. It measures 2-1/16" wide x 15/16" thick x 4-3/16" tall. Comes with the sheath. Switch has 2 settings - one for the flash light then the 2nd for the zapper. The usual international WARNING APPLIES.
