Doesn't work as claimed
Don't buy this. It doesn't detect anything. Not recommended at all.

Indispensable pour repérer les rails derrière le placo
J’ai pris ce détecteur de rails de placo un peu par curiosité au départ, et au final je ne peux clairement plus m’en passer. Pour repérer les rails derrière le placo, c’est ultra pratique et ça évite de percer au hasard. Il est simple à utiliser, la détection est rapide et suffisamment précise pour savoir exactement où visser ou percer. Depuis que je l’ai, je gagne du temps et surtout j’évite les erreurs bêtes (mauvais trous, chevilles inutiles, etc.). Que ce soit pour fixer des meubles, des étagères ou faire des passages propres, ça change vraiment la vie. C’est le genre d’outil qu’on ne pense pas forcément à acheter, mais une fois qu’on l’a, on s’en sert tout le temps. Très bon produit, fiable et vraiment pratique au quotidien.

Funciona correctamente
Era muy escéptico, después de haber probado otras soluciones. Me sorprendió gratamente la capacidad de detectar objetos detras del pladur. Lo recomendaría. Aunque me parece bastante caro para lo que es.

Batteries Not Included
This is a capable stud finder and it does the job well once you get started. The multi-sensor layout gives a clear indication of where studs are, which is exactly what you want when working on walls. To be fair, they do state that rechargeable batteries are not suitable, so that part is on me. However, the fact that batteries are not included could be made clearer. It has a touch of that old sci-fi film warning about batteries not being included. The other irritation is the button. You have to keep it held down while using it, which makes it a bit awkward to handle. An on/off switch would have made it much easier to use and freed up your grip. These are small design niggles rather than faults. Overall, it works well, gives reliable results, and does what it is meant to do. Just be aware of the battery requirement and how it operates before you start.

Unreliable results
Works unsure… keeps flashing different over the same place, so i ended up pulling the fodder off to see the drywall screws and determine where the studs are. Disappointing…
