Bests & Worsts Reviews from Amazon

Painfully loud...REALLY. The way this item works is there are two devices; one on your keys, and one you keep handy in case you misplace your keys. You press a button on your device you kept handy and it SCREECHES a VERY LOUD signal to the other device attached to your lost keys. It does work, however you may have to move around your house and try more than once in case the keys are under a sofa cushion, etc. And if you can't find your handy device, you can use Key Ringer's website to play the horrible screech to call for your lost keys ([...]), Funny but true: it is so loud, that the chronic key loser in our house has not misplaced keys since we bought these because they hate the loud screeching signal! So you can say this device works in more than one way.
