I haven't used this for a general application, although I've noticed high EMI in some of my commonly used outlets around my house. I did some basic testing where I knew EMF would work and definitely confirmed that it works, so 10/10 for that. But for ghosts I used this at home and nothing really happened so it made me think this thing wasn't actually working. BUT I took it to my buddy house and we confirmed through multiple events that the place is spooky and we got timely answers by turning off the meter. 100% recommended.
