Bigbruin.com posted a review on the KeySmart Pro Smart Key Organizer With Location Tracking
A quote from the article:
While most of the KeySmart key organizer simply organize your keys like a Swiss Army knife, the Pro model adds a few additional features that turn it into a smart device. In addition to an LED flashlight to help you light up any key hole, the KeySmart Pro also has a USB rechargeable implementation of Tile's location tracking technology built in. You will not only be able to keep your keys organized, you can find them using the Tile app on your phone.KeySmart Pro Smart Key Organizer With Location Tracking Review
