Ghost detector
Works as described, bought it because it's the exact one from phasmophobia and my son loves checking the house for ghosts with it.

Affordable seemingly accurate meter
Good basic EMF reader. I have never tried a higher end one but this gives basic readings and seems pretty accurate! When I read the EMFs on my iPhone, it is super high but when I turn on airplane mode it immediately drops to nothing so it works. Very useful to get a sense of the worst exposures in our house without spending a fortune. It seems to only work very close to the emitting object and doesn’t sense waves once backed away 6” or more. Idk if other meters detect EMFs farther away but I was interested to see how far the waves would travel outward from the object and I don’t think this can tell me that or perhaps that’s not possible to really measure, idk. Anyway I do recommend to get an inexpensive basic read of EMFs.

Great
Works very well. I got it due to a roommate who thinks the wifi is toxic and kept puttingtinfoil over it, which blocked the signal for the rest of the house. The wifi box is in the main room rented, but its located on the top shelf. Long story short, his room is the safest in the house. Having the wifi box very high, does not radiate anything toxic even at head level.

Easy & interesting to use
Conveniently, it came with the battery installed. The device was easy and interesting to use when I tested around the house. I had a surprising result at the control panel of my kitchen stove/oven. Since finding that out, I try to avoid standing in front of it too long while cooking. The cell phone makes the device light up completely at certain points of use. The Wi-Fi router also caused full red light-up that extended several feet. A microwave oven was the most pronounced - Red across the entire room! I also plan to take it with us on trips, especially if we stay or visit sites known to be haunted. Update: The device lit up like a Christmas tree in a paranormal location.

Soooo bright
It seems pretty accurate. It comes ready to turn on with the batteries installed, which is nice. But dear lord are the lights bright on this thing. It's hard to look at the green lights straight on.

Works great for electronics.
You can see this works great when you go near TV, microwave, computer, etc. Haven't found a ghost yet though, reason why I bought it.
