A brief review of an inexpensive (about $22 USD) RF detector / meter.

I noticed after finishing that they had put a sticker over an older version of the product on the box.

These are the values the manufacturer claims:
Electric field strength: 0-9999.9v/m
Magnetic field strength: 0-9999.99μT
High frequency/power density: 0-9999.99mw/㎡
Detection accuracy:
Electric field strength: 0.01v/m
Magnetic field strength: 0.01μT
High frequency/power density: 0.1mw/m³
Frequency ranges:
Electric field strength: 20Hz-100MHz
Magnetic field strength: 20Hz-1MHz
High frequency/power density: 50MHz-5GHz
