Never lose your keys again: Smart Key Finder
Losing my home keys around the house is probably my biggest problem, since I need at least 10 minutes to find them. Now, all these can be gone for good with this Smart Key Finder. The system is pretty simple. All you have to do is attach the colored receiver to your keys, and whenever you lose them, just push the button on the wireless transmitter. The keys will beet thanks to the wireless receiver and you will know in no time where they are.
