Rechargeable EMF Meter, Radiation Detector, Electromagnetic Field Tester, Smart Counter, Great Reader for The Home, Office Or Ghost Hunting, Handheld Digital Sensor, Red

Its very easy to use. Many of the bad reviews seem to be people who couldnt do a simple Google search to understand ųt and v/m. Just look it up people. I can't say how accurate it is because I don't have a certified lab quality tester to compare the results. However, it is consistent which tells me it does work as expected. When you get a reading, you can move away, come back, and you get the same reading. Other devices like this seem to have issues getting a stable or consistent reading, which would make me question if its actually doing anything except generating random numbers. This device is very consistent. The results can be changed by changing the electric flow(turn a fan up or down) and the device reflects those changes. For all those reasons I believe this product works as intended, and I trust (can't be certain) its accuracy.

assuming this is working effectively, I really am glad i bought it! It is very reasonably priced, well-made, easy-to-use, and gives me what appear to be good warnings

It didnt come charged so you take the cable and plug it into a power supply you already have. Leave it charged for 3-4 hrs. It says you need to calibrate it but u don't. I wish I understood how to read it better. No book skimpy instructions no power supply only a usb cable. I just used the one that I charge my cell phone with. My cell phone read dangerous radiation levels. I will be down grading. All I know is red is bad, yellow is ne careful and green is ok. I will have to keep studying how to use it.

I chose this EMF meter over analog meters because I like the ease of calibrating. It's easy to operate and to read what the meter is detecting and even lights up the display red when getting too close to potentially hazardous electro magnetic fields. I plan to use this meter for upcoming paranormal investigations and am excited to see what happens in places reputed to have extensive and frequent activity.

Cracked it open and the battery was dated 2005, bought in 6/21 now I had to order a new battery and solder connectors to get it to work again.

It's highly sensitive. It was able to pick up very lines in the ground and show a clear difference between light pole and a electrical box. Readings feel accurate based on things tested. But you got to move slowly and stay still, any hard bouncing or walking, will cause spikes in your readings.

Bought it because it was cheap, got what I paid for.Instructions tell you nothing other than how to turn it on.Readings... no clue what they indicate, sporadic and haphazard at best.No readings at all on many objects unless touching them?Says self calibrating, but have to push button 5 times (which found out from the questions section here.No online help, guides, specs, anything.Don't waste your money.

Great product. I would buy it again!!
