Title: Piece of junk
Review: Bought this to check around the house for radiation.I guess you get what you pay for. It buzzes ALL the time. With the sensitivity down, nothing, with it up, all the time...even 500 feet from the house out in the country in the middle of 20 acres in a 'dead' cellphone zone.I'd send it back but it's not even worth the postage. And the instructions, you would think Chinese manufacturers would keep at least one person on retainer to translate the instructions to something at least resembling English....no, not even that....
