Magicfly Wireless RF Item Locator Key Finder 1 RF Transmitter and 6 Receivers
Love love love!  I bought this as a gift fort husband to add a little sanity to our mornings.  Now I don't have to jump up and help him find his keys in the morning.  If only they fit nicely in his wallet and phone I would be in heaven but I will take what I can get. We have used them numerous times already.
