Ne fonctionnait pas à la réception! réparation de fortune! tout fonctionne parfaitement maintenant! modification de l’alimentation du piezo avec une broche de test probablement à l’intérieur.

This water leak detector is excellent in sounding a very loud alarm in the presence of a small amount of water.Also has a light that illuminates at the same time the alarm sounds .Uses a 9 volt battery that will last a year or more.

I have used many of these detector alarms and they work great at very small amounts of water(.2") depth and have a very loud alarm. Uses a 9volt battery (alkaline) and lasts about 10 months to a year

I get water in my basement every spring and when we get a ton of rain. Like when it rains for a whole week. This is a fail-safe alarm for when the sump pump stops working.

Robusto y de buena calidad los materiales. Tras colocarle la bateria y hacer la prueba, ha funcionado perfectamente. Lo recomiendo

Around 50 days long shipment, quality seems to be ok.

Very loud and sensitive! Exactly what I needed.

good
