It works perfectly, put it in my Keychain and dog
It's really a miracle. For those who keep losing keys, wallets, cats, remote controls and more, this small device has always been a lifesaving tool. They are easy to install. So far, they have played a very good role in my staged experiments and at least two actual "misplaced keys" incidents.
Very good to have
I bought this for my wife. She has a memory like a goldfish. She is always nervous because she can't find his keys or wallet. We had to turn the house upside down and look for them, only to find that she left the key in a very random place … She was very happy to receive this, we had a simple test, it worked very well and found it soon!
