This smartphone-attached “panic button” has a few alarms built-in, both audible and discreet. When triggered, it’ll bypass the user’s locked home screen to contact the Katana’s response center which, in turn, can contact “local emergency services and/or up to seven friends and family.”
This is the lowest price we’ve ever seen on Amazon. But just a heads up, you’ll only get 1 month of the response service for free. After that a subscription is $15 per month but there’s also a $144 annual plan, which saves you $3 each month.
