Rated 5 out of 5 by from Key finder Works great!! I'm happy that I bought it. Now I can find my keys when I miss place them within my home. I am surprise how strong the signal is. Did not think it would work when my keys were in a closet but it did. A good price as well as I bought 2 of them. 1 for both of us.

Rated 4 out of 5 by from Tone too high pitched Perhaps a major group who needs this item is older Americans--seniors. Yet those of us with some hearing loss find the alert tone so high pitched, we can't hear it unless we're standing on top of it. Not very good, that. Would benefit from a tone with a lower pitch. Set up and function seemed fairly easy to do, so that's a plus.

Rated 4 out of 5 by from Better than nothing. The beep isn't very loud but it's better than nothing.

Rated 4 out of 5 by from works okay, wish it was cheaper I purchased one for my wife's keys when I purchased new phones. I'm not sure why they are so expensive, as I would have gotten several if they were not. It is not too big, which I was afraid it might be from the picture. Like others have reported, it is not very loud, and does not even begin to beep until you are within a few feet of it. The phone handset does a decent job in getting you to the approximate area of where it is, and when you are about 3-6 feet away, the detector begins to beep, which you wouldn't be able to hear from farther than 6 feet away. I would buy more if they were cheaper.

Rated 2 out of 5 by from Not as useful as I expected The sound on the fob is very low. The handset sometimes increases beeps even when you're not getting close to the fob. The fob beeps of its own accord sometimes when it's hit or moved - this has nothing to do with trying to find it.

Rated 3 out of 5 by from Should be a big help. I have only used the key finder in "test" situations, not a real loss, but it seems to work well and be easy to use. If I should lose my key within the house, it would definitely find it for me.
