Whether it's your keys, your wallet, your luggage, or your dog, tracking down what you've lost may not need to be as tough as it used to be. No need to be like Dory from 'Nemo' with this nifty device!

This Smart GPS Tracker is super compact and could slide right into a pocket or attach to a key ring, and you can get one on sale for just $21.99 ahead of the new year.

Finding this bite-sized tracker could be a whole lot easier than trying to remember where you put your keys. By sending updates in real-time to the Findmytag app, this iOS and Android-compatible tracker could make it much easier to locate your luggage, keys, and even your pet. Paris Hilton would approve!

The lightweight design is subtle and unobtrusive, and you can even tell the tracker to make noise, so you aren't relying entirely on the map. Plus, this GPS tracker has a 220mAh battery that can last up to one year of continuous usage, and your purchase also has a one-year warranty from the manufacturer.

No more wondering where you put your keys!
