The Orbit family of Bluetooth trackers will help you locate valuable items in seconds using a free iOS or Android app. The various shaped trackers physically attach to a wander-prone item. From your smartphone, use the app to page that item when it goes missing within a 100 foot range. The tracking device can also be used to page the smartphone in reverse, even when the phone is in silent mode!
Orbit Glasses attach to the temple of your glasses. Stop losing your stuff?
