This Bluetooth-enabled key fob promises to help scatterbrains like me keep track of their keys and Android or BlackBerry smartphone by giving a notification when the two are separated.
Read more about the Cobra Tag.
At about 2.25 inches tall by 1 inch wide, the Cobra Tag fits easily in a pocket with a few keys on its ring.
A Micro-USB port on the bottom edge of the unit facilitates charging with the included cable.
The speaker on the back of the Cobra Tag is small, but it's quite loud.
We used the Cobra Tag to keep track of our keys, but you could attach it to a backpack, a purse, or any other item you'd like to keep nearby.
The free Cobra Tag app for Android or BlackBerry is where you can adjust a variety of settings and view the status of the Cobra Tag device.
When separated from the Tag device, the Cobra Tag app will mark its position on a Google Map.
In the event that the phone is the half of the equation that's missing, the app can also lock the phone with a PIN and send out time and location data via e-mail, Facebook, and Twitter.
