Unit Activated. I repeat. Unit activated!
Bought this EMF reader to check for rogue frequencies in my house. Within minutes it began chirping in Morse code and spelling out “LEAVE” under my fridge. Took it outside. It flatlined until I passed under a lamppost that has “never turned off since 2008.” Suddenly it lit up like a Christmas tree on parole. Brought it near my phone? It went full DEFCON and whispered “they’re watching through the charging port.” Tried it on myself—nothing. Tried it on my cat—she levitated. Most disturbing: when I passed the reader over a box from Amazon, it buzzed softly and said “Prime Directive confirmed.” Not sure if I’ve awakened the device, myself, or a retired DARPA entity living in my walls. Either way, it now rides shotgun and refers to me as “Operator.” 5 stars. May or may not have summoned surveillance drones. Would buy again.

A Must-Have for Any Ghost Hunter 👻
Our goal was to become YouTube ghost-hunting stars, and that requires the right gear—this EMF meter was the first must-have on our list! ✅ Easy to Use – Just press the button once, and it instantly activates the sensors to detect electromagnetic pulses (or something spooky 👀). Press it again to turn it off. ✅ Battery Powered – Uses a 9V battery, which is easy to replace by removing the screws on the back. ✅ Essential for Paranormal Investigations – If you’re starting ghost hunting and can only get one tool, this is it. Whether you’re chasing spirits or just curious about EMF fields, this meter is fun, easy, and a great addition to any paranormal toolkit! 👻💀

Depends on what you want this for
I mysteriously lost my old K2 EMF meter following a haunting investigation. After searching everywhere, I ended up buying this as a replacement. Though it works (I tested it close to my router and working microwave oven), but it is FAR LESS SENSITIVE than my old one. You have to have this very close to the EMF source for it to activate. For hauntings and paranormal use... I cannot recommend it. To get it to react, you would need EXTREME energy very close to it. May be just this one unit; I dunno. But I hope I eventually find my old K2.

Good tool. Doesn't have sound effect.
This one dies not make a noise when it detected emf. But that's my bad,I didn't read through.

You get what you pay for
Very clicky, plastic button. Cheap unit. Works but needs to be used manually, it will not “go off” on its own unattended if you are looking to monitor supernatural activity. Also no sound, only light and meter reading. Ok if you want to see if your tv or electronics are giving off high readings.

Great for ghost hunting and casual use!
I primarily bought this to go ghost hunting, and have definitely caught some interesting & unexplainable readings with it! But also, just going around the house and testing all the electronics is both fun and eye-opening to the ammount of electromagnetic energy we subject ourselves to. Put it up to a microwave, it's kinda scary how far back you can go and still get a reading above green! Definitely worth the money. It's easy to use, comes with instructions, fairly sturdy and works great!

Works well to measure electromagnetic fields
This works well to detect electric fields in the house. I found that my computer desk heating pad showed a high field intensity, and also the wireless charger for my cellphone, as well as the laptop. The plugs, cables, lights and devices near my night stand only showed a low field intensity which died down 50mm (2 inches) away from the items. So no problems with sleeping. Good product for my purpose. May not be appropriate to measure exact numbers in which case there are more expensive gauges available.
