I love this thing. Like other people have said,the little screws are a pain. I've lost one so far. So far I've put this under the passenger seat in the car & under the car by the back bumper. Regular batteries have lasted me a week. One day I'll read the instructions on how to use most of the software. I only use the Google Earth to she where it's been and that is fine for me. If you're worried about it being blocked by metal, don't be. It works great.
