This device is a lifesaver, I’m one to always lose my keys.  So far they work no matter where they are in my house.

These work great. Just wish they were a bit smaller.

My darling wife has a habit of leaving the car keys in random places - her coat pocket, her handbag, even the car.  It has been the cause of some tension between us that I can't find the car keys when I am ready to leave.  Now, with this product, those fights are a thing of the past!  I simply push the button and hear the beep and trace it back to which coat or purse she left the keys in, and I'm on my way.  Much cheaper than a divorce attorney!

Good

Just what I needed.

worked fine for 3 months, then quit working ...even with new batteries.  it was never dropped or abused or anything.
A month later now, I'm upgrading my review....  They saw my comment and sent me a brand new one.  Great Customer Service!

It works well indoors. It was pretty quiet under several papers or under a throw blanket. It turns off easily. It takes a about 30 seconds to activate after you push the button. It is not ear-piercing like my DISH remote finder.

One of the most useful items in the house.  Beats having to tear the whole place apart just to find the darn keys.

Terrific little finders

This little gizmo works pretty well, and my husband likes it (which is the important thing, since he's the one always losing his keys). Be careful with the battery cover, though. Some of them didn't fit in good and tight and had a tendency to fall off. A piece of tape helps.
