Muy bueno para encontrar llaves perdidas.

My husband always forgets where his keys are- had to do something that would
help. It does work. Note that if your key finder keys are in your purse, the sound is much lower but still
audible.

I have been able to find keys and wallets when I was in a frantic hurry. A life saver.

Very good

Batteries last a long time. Batteries come with it. You cam stick it to something or use it as a keychain. I have them on my keys and remotes. I can hear it from downstairs or in another room.

I put one tracker on 3 separate key rings (it comes with small key ring attachments) and used velcro to attach the last one to our main TV remote.  If these things were smaller I would put them on tons of things that tend to get lost.  I considered putting one in the phone wallet as it is slim enough to fit, but ultimately decided it didn't need one.  Easy to set up and easy to install.  Oh...FYI, when you install the battery in the remote, you will see a positive sign (+) that seems to indicate which way the battery is installed.  It isn't.  Install it the opposite of the sign.

Easy finder, even my dog:)

what a great gift for anyone who sets things down!

Works all through our house.  We have a 2 year old that likes to hide keys, but this device is the great equalizer to his schemes.  :)

The Esky keyfinder is so simple to use.  Setup is just putting in batteries (included!!).  Works flawlessly.  It almost makes me want to misplace my keys so I can use it for more that testing.  The unit comes with 6 receivers.  It came with rings for attaching the receivers to keys and also has velcro for attaching to things like remotes.
