It's a bit unclear, I'll return it.

As a climate control tool, it is very useful as it checks if there is voltage and measures temperature, in addition to distinguishing between phase and neutral cables and indicating 3 levels of voltage, and I believe it even detects if they are unbalanced.
It fails me
The temperature probe should be longer to be able to use it in ducts and, if possible, in the form of a needle instead of the American plug.
The 3 voltage levels do not specify a range in the instructions, for example low below 200V, high above 450V, I will have to test with a regulator.
The high sensitivity is too sensitive, I don't know if it's detecting electromagnetism or static electricity, I'll have to keep testing to use it on embedded cables.

The delivery is made to the same address, but it cannot be left in the elevator, because if I don't receive a notification through the intercom, anyone could take it.
E
It's a nice device. It's just that I'm now scared by how many electromagnetic waves are around me. On high sensitivity mode, it beeps practically all the time inside my work space. It works properly. I recommend buying it.
G
Useful, but it's difficult to remove the batteries because they get stuck easily. Despite that, it's a good product.
P
It's easy to use and detects well.
