Detects cell phones just fine
It does precisely what its advertised to do.
This is just what I was looking for
I still haven't found a GPS tracker so this is very good
I couldn't believe it found a tracker my husband put on my car. We are currently going through a divorce and he talked my son into putting it on my vehicle. I drove over it with my car and dumped the pieces in the trash!!
Tested it with my iphone and it definitely works. Whenever I do anything with data (like make a phone call or get called) the thing sets off and vibrates like crazy. Keeping this in my car since there's probably a gps tracker on it
Arrived in a plain brown envelope like the information stated.
I travel a lot, and I've been using this to check my room for any sort of tiny spy camera. I have not found any, but I do know it works because I tested it with my Galaxy Note camera and it blinked like the description says it would.
