For this price, I am evaluating only one of its features, which is very useful to me. Yes, it is 100% not accurate but with a new battery you can find the following very important things for buildings: 1. Distance of connectors in a column or beam, and even if you break a corner you can see the cross-section. 2. Number of longitudinal reinforcement bars, e.g. in a column (here with reservations because you go deeper and often miss some reinforcement elements or get confused if some are very close together). The bars must have little overlap and be few in number, but who can say they haven't encountered countless houses with three rods per side or even one at each corner, old constructions? So here too, in many cases, it is useful. 3. Distribution in buildings. It helps you find structural elements like columns and beams embedded in walls.
Yes, it is not a specialized instrument for this job but for this money you always have it with you, it is light and you are not afraid of it getting damaged. You immediately get an idea of what is in front of you.
Regarding what they say about drilling with a bit and not finding rods, I have done it and had successful results (maybe there is a different production series?). For better accuracy, it requires a bit of careful handling by watching the indicator, which is the point where it shows an increase. I have not used it for electricity.

Unreliable tool. Above all, with the flow of electricity, it showed that there was no power. When I removed the cover, it showed that there is power. In another case, it showed that the power cable runs right below the beam, while it was actually 10 centimeters below the beam. It only detects the iron of the beams at a short distance, but not in the correct position. I drilled with a drill bit in many points where it showed that there is iron and I couldn't find it. Good for playing, not for work.

    This review is about a variation of the product

    A very disappointing detector regarding electrical wires (it doesn't beep even above the socket or the switch), it easily finds metal inside poles, I haven't tested it for wood. I bought a Chinese one from Aliexpress (KAIWEETS-KES 01) and it finds the wires inside the wall.

    It will help you avoid nails in the wall, but it will struggle in the corners. Maybe I'm not using it correctly, I don't know. Anyway, I don't know of anything better for this price.

    Unfortunately, I wasted my money! It can hardly catch cables at all! Not even when they are loaded. Don't buy it! I will check if it's still under warranty to return it.

    update: The problem is severe when the cable is deep. It finds them more easily on the surface.

    Easy and convenient product to use and read the indications. It is quite good at finding metallic elements on walls, but only if they are isolated. In the case of wanting to measure on reinforced concrete or beams, it gets confused and often gives incorrect readings, making it practically useless. Its effectiveness on drywall was good, but keep in mind that these devices need to detect current flowing through the cables to find them. If there is no current, they won't detect anything.
    It has good features and if it cost 15-20 euros, it would be okay. At 70+, it is completely impractical and I cannot recommend it to anyone.

    It finds cables under voltage and metals with fairly accuracy, but it deviates about 3 cm parallel to the current conductor. Good build quality.

    This review is about a variation of the product

    In metal, with calibration, it performs decently, although with some minor flaws.
    It does not reach a great depth.
    In the electrical conductor, it performs poorly. It only achieves accuracy when parallel to the conductor. Accuracy across the conductor is as if it has the eye 2-3 points higher. Caution!
