Three-hundred-and-twelve-thousand-four-hundred-and-ninety-six. That's the number of times I have misplaced my house key. And it is rather strange that my brain still prefers to maintain an exact count of the recurring mishap rather than the exact location of the key once I am done with it.

But there seems to be light at the end of my tunnel of poor memory - the Radio-Controlled Key Finder. The Radio-Controlled Key Finder consists of a fob and a "credit-card transmitter". You attach the fob to your key and forget all about it. When you need to retrieve the key, just press a button on the transmitter and the fob starts beeping and flashing to let you discover where the little rascal is. Simple, huh ? The radio-controlled device has a range of about 80-feet - enough to alert you even you have left the key behind in a neighbor's house. The contraption is available for around $23.

The catch - I must now remember where I left the transmitter.
