I love wallets. I have owned many wallets, which in part is due to the fact that I am always loosing my stuff.
If like me you have a similar problem but aren't so happy about the prospect of picking a new one the Wallet TrackR may just be for you.
It's not super thin but it is a great way to keep track of your wallet and other valuables if you are desperate not to loose them.
