Meter is very sensitive and lets you know the Likely type of signal your receiving . Cell phone or router. Lots of versatility in ways to see data. Well made and easy to use. Nice instruction booklet. I would recommend this product.

This meter packs a lot of information into a small, hand-held device. EF (electric field) and EMF (electromagnetic field) at 300Hz-100kHz and RF (radio frequency: 100kHz-300GHz) frequencies are detected. All three values are shown at the same time with their appropriate units. The display can be modified, and values shown graphically instead of digitally. A spectrum analyzer display shows the detected RF frequencies in real time. A User Menu is used to set initial values and options. The device retains and shows the current date and time. There is a speaker and a way to set audible alarm settings. A USB-A cable is included to connect to your PC with downloadable software. This cable also serves to recharge the included battery via USB. Four front panel buttons are used to navigate the features. A nice instruction booklet is provided along with a small card showing safe and dangerous levels of radiation. I'm just beginning to investigate what all this device can tell me about my surroundings.

I haven't spent much time with this meter because the directions are very sketchy..with time I hope the internet will give more info on how to read it and to simply use it.

A little complicated to understand, but easy to use. Keep the reference material. We found a higher than ideal energy frequency at our bed's headboard, that when we touch it, our energy is affected and yet the headboard is simply wood, leather and batting - no metal!

I looked at several EMF meters on Amazon. The most recommended was close to $200 which seemed high. This one is a reasonable price and works WELL and EASY! I'm a novice but wanted to check the usual suspects: computer, phone, microwave, router. I was pleasantly surprised by how incredibly easy it is to use. It gives you three ratings and can record the ratings, if you choose. Our microwave was very high in everything; digital clock on nightstand in bedroom also high (and gone), router not bad based on where it's located and so forth. The phones were lower than expected. I highly recommend for someone who just wants a clear assessment of EMF/RF/EF rates in their home. Now I can accurately assess further steps.

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!

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

Like the product, handy to have! To read the EMFs, EF, RF around the house re Radiation, etc, especially, from Smart Meters.

The unit I received appears to be taking fairly accurate readings for RF, EF, and EMF, and shows changes as I move to and from sources that accord with the patterns one should observe theoretically. This is all to say that, for a consumer grade EMF meter, I feel like I got my money's worth for assessing and troubleshooting healthy exposures in different parts of the house. In particular, I was able to confirm that our relative RF exposure in bed to a WiFi router right below our bedroom is well within reasonable exposure recommendations (but most definitely not right next to the router). It has more functionality than I can use and is highly configurable. And for those science geeks out there who want to plot and monitor and analyze emissions more ambitiously, the unit comes with instructions for downloading software to do so (as well as a handy reference card). Great value for the money and happy I bought this over a more expensive but aesthetically more pleasing competitor. Also, it came with a 100% battery charge and I still have nearly a full charge after multiple tests.
