Very important tool to maintain both privacy and accessibility. you can't keep everything in a safe and sometimes you need to share your things. It uses Low Energy Bluetooth 4.1 and the price seem fair as long as it delivers. The concept itself is cool.

I like having many colors to choose from too. The app notifications can also be very helpful if you want to track things down. But this can also be a double edged sword if someone gains control over your app. Great Hunt!
