Wireless RF Item Locator/Key Finder with LED flashlight and base support. With 4 Receivers
This works fine for finding<br />&#34;lost&#34; car keys, which are generally nearby. That it comes with 4 units for things that get lost and only 1 finder is out of balance; most people do not have 4 things to track, since this system absolutely does not work on my iphone. There is the minor issue of remembering which color tracker you put on which important device, but I suspect people just punch the buttons until they hear a signal. It really does wor at 50 feet or more.
