Prévient le vol

C’est fiable et prévient le vol près des portes d’entrées. Il est en fonction depuis 2 1/2 ans sans problème. Nous avons branché le tout sur ports USB. Très fiable. Je recommande

BON PRODUIT. PRIX SUPER.

Acheté pour détecteter mon chat lorsqu'il veut rentrer à la maison, il a très vite compris comment cela fonctionnait. De la s'cousse , les humains sont aussi détectés et eux aussi ont compris comment ça marche...! (Pour certains ...)J'avais peur pour l'usure des piles , cela semble resté correct.L'avantage c'est : pas de fils et choix de mélodies, très facile à programmer.Très content du produit, prix attractif et fait le job.Belle journée à vousLaurent
