### ⭐⭐⭐⭐⭐ Review
*by M***O on 27 January 2026*

È un articolo molto semplice da montare e che funziona senza bisogno di collegarlo a niente. Bisogna svitare le tre viti per aprire il guscio e mettere le pile. Se si utilizzano le linguette metalliche le viti sporgono leggermente sul fondo permettendo un contatto con il pavimento. In questo caso basta una minima quantità di acqua, anche solo uno strato sottile, che l'allarme inizia a suonare.
