Great design
Love the concept. Lots of useful information and seems to work around phones and microwaves - it definitely has a reading for each.

Not 5G!
Not suitable for what I wanted it for. . got no reading at all from 5G masts . . however, wi-fi seemed to work OK. . .it's possible that the unit was defective. . but I had no way of knowing. Pity, as the Meter is well made and easy to use. . so gave it 5 stars for that!

Works well
Just got this. Works very well as a general emf reading device. Surprised how much emf comes off my Samsung. . The 3 way screen is very handy, no need to turn nobs. Recommended.

This EMF Meter works great! It is a great value for the price! It comes with simple written instructions, which is much more convenient than going on the internet. Reading and using the instructions is very important, until you get use to using this device. It is handheld, light and very portable. It also has a chargeable removable battery, and this unit can be directly charged with the supplied USB cable. You can't go wrong by buying this device!

I am an amateur so all the readings are a little archaic to me, but I bought it for a narrow use which it seems to perform well.

The tester is very easy to use and comes with a nice simple software app for downloading your data to either Windows or Mac. It will record up to 24 hours and the battery is rechargeable and it retains its charge very well. In my usage it only used 22% over almost 20 hour of testing! The application is easy to use and the software installs perfectly and the data is easy to import into Excel. The tester even comes with reference card for values. I had a question about some of the readings and emailed Tech Support; I got an answer within hours! After tryin other testers, the EMF-390 is the best I have seen, and I feel very comfortable with relying on the measurements it is giving me. The data logging is crucial if you are trying to study events over time. The tester also tells you where to hold it so your body does not impact the readings. Well worth the price!
