The 'Wiso' is an emergency whistle that uses Bluetooth to alert up to seven chosen contacts when it is used. The whistle does this by connecting to an app that can quickly text, call or email loved ones with your GPS location.
The emergency whistles are small and lightweight, featuring a stretchable rubber strap that allows you to have it close by wherever you need. The battery is made to last for up to two months, upon which time it should be replaced to ensure that your contacts receive your alerts in the event of a physical attack. The device was made to offer a piece of mind to its users, letting them know that friends and family are easily contacted if they need help.
