You always forget where you put your keys? Haven’t you found a solution? Check out Fetch My Keys keychain, maybe it’s a perfect solution for you.
As we can see from the images, this is a dog shaped keychain that measures 45 x 45 x 12mm and weights 0.018g. The key ring is bites by the cute black dog in order to attach your keys to the keychain. Most importantly, a sound sensor has been integrated into the dog shaped keychain. When you don’t remember where you left your keys, just whistling will set off a beeper inside the keychain and cause the dog’s nose to flash so that you can quickly find out your keys at home or in your office. Of course, it can also be used outside, but you’d better know the approximate location.
Fetch My Keys keychain is priced at £5 GBP (approx $8.2 USD). If you’re interested, jump to SUCK UK for more details.
