Excellent if you know how to set it up correctly and use it, I had experience with other models so it was easy for me, because most of them don't have a manual inside.

Initially, for the detection of any kind, some knowledge of radio frequencies is already required so that the person searching knows what they are looking for.
This particular product is mediocre to bad. It does not pick up simple MHz transmissions that are within the spectrum mentioned by the product. It only detects strong magnets, which is somewhat reasonable…

It is a serious product, but many believe that they will get a machine that will tell them "Good morning" and where the camera is. It doesn't work like that, but it detects which devices are emitting. Now the "infrared" mode is a bit of a joke, just a light that shines if the lens is polished. Practically, it detects which devices are emitting wireless signals, and this requires some searching and adjusting. The downside is the nonexistent guide that doesn't explain even the basics

It does what it says, simply due to its complexity, it takes a little time for the amateur user to learn

It broke almost everywhere. Maybe I didn't know how to work it, maybe I just needed to get a different machine for what I needed... If you want to find faults in the house, I do not recommend it... I wasted all the outlets for nothing
