REVIEW: Cheap meter … very cheap! in fact is a meter already seen with different shapes, as sometime happens with Chinese products.
You will find this meter in 5-6 different shapes, with similar display and buttons.
Is a meter for low frequency magnetic fields, for electrical networks and power lines.
Not good for radio networks like phones, wifi, etc..
The quality is very low, and the accuracy doesn’t really exist, we can only see field differences but not accurate.
MY PERSONAL OPINION: Always the same meter that we have already seen many times, almost a toy, you can see aprox field variations only.
