If you enter the PIN number backwards on your watch, the police will come.it's a fucking 22 pistol, which makes it useless
you have to enter a pin on your magic watch before you can fire it, which makes it even more useless.
if the watch gets broke, No Gun
if the watch gets wet, No Gun
if the delicate electronics inside the gun break, No Gun
and even if everything works perfectly,, it's a .22, so... No Gun.
if that is a "smart gun" where are they gonna find people stupid enough to pay $2000 for a .22 that may or may not fire when you need it?
