Anybody here use a key finder/locator?

One of my daughters loses stuff all the time (keys in particular). I'm looking for one of those fob-type locator dealies to give both kids for Christmas.

Any good ones out there?

Nevermind. I just found these:

Reviews seem to like 'em, so I bought a couple. I hope they work.

received these for Christmas last year. Utter garbage. They kept on beeping randomly. Too big on the keychain
