POOPFIY 4G 5G
this meter is presented as “4G – 5G”, but in fact is only a meter for magnetic fields of low quality, it can NOT measure 4G and not even 5G… and not even 1G !!!
The descriptions of these items push you to doing a WRONG purchase!
As happens for many oriental products, the same software/hardware is installed on different boxes with different shape and colors, and sold as a new device, in fact is the same 20$ detector, presented in 20 different shapes!
MY PERSONAL OPINION: it is just a cheap meter for low frequency magnetic fields (50hz), is not accurate and you can find it in different shapes at half of this price! BE CAREFUL!
