Such a simple idea that works so well!
I'll never have to ask any of my household members to help me find my keys again! Result! ????
My only grouch is that after using it (to find my keys) tyre times, for less than a grand total of one minute, it's battery needs replacing (one of those disc type that usually cost a few Bob).
I wasn't expecting a top notch battery to be included, but that is poor show.
