This bugger will knock the socks off an unexpected attacker. Not only is it easy to carry, but it puts out a million volts. The hard ABS exterior is durable and resists damage. Recharge the Ni-Ca battery with the included 110 V charger wire. A matching pouch will be provided with every Pro Firefly. The wrist strap will assist in handling this stun gun. Allow the battery to charge for approximately 8 hours for the first charge.
