After I stashed my car & house keys in a sweater pocket and put it away in a closet, I'm in panic mode. Replacement of the key fob is $$$$ and no after market sellers.
Well my brain cells began to work up firing power and I did recall where the keys might be, and they were. However, it took me hours of tearing the house apart to find them.
This little tracker chip is perfect and reminds you if you may have even thought about leaving them somewhere. I got one for my CGM reader too. Didn't need one for the disappearing phone as my Garmin watch will find that. Can't say how long the battery lasts as I haven't crossed that bridge yet. But so far I'm pleased with product.
