This is probably one of the best inventions of recent years. Probably we all have happened that we can not find our keys when we get out or we have lost something important that we urgently need. According to my grandmother, you have to put a glass upside down so that things appear, but I personally prefer to use a more modern method and not so superstitious.
I'm talking about StickNFind. What is StickNFind? It is a round sticker whose size is a bit larger than a fingernail and can be detected via Bluetooth. Simply place it in our keychain, necklace on our cat or any object not want to lose sight, to track the sticker then just use a smartphone or a tablet that has Bluetooth.
The StickNFind has its own batteries that need to be changed once a year or so.
