This is the real deal in tasers, not some Chinese-made POS that runs on a 9V and goes dead quickly; this uses a long-lasting lithium-ion battery.
Good up to 15 ft and disables your attacker for 30 seconds. Connects to the "noonlight" app on your phone and will alert law enforcement when you fire your taser.
With a certified police report, Pulse will replace your taser free of charge if you have to use your taser in self-defense.
It is legal to carry tasers in CA without a permit, as long as you are over the age of 18 and no felonies.
40-50k volts, make that Chode that attacks you ride the lightning for 30 seconds. They won't want to get up after.
