"About 3 weeks ago I bought two of the water alarms...four days ago Tropical storm Debbie was approaching and I put one of them in our bedroom where there had previously been a roof leak. When the storm hit the roof leaked again. As soon as the carpet got wet the alarm detected it and we were able to take action and kept the damage from becoming much worse. This is a great product. And the price is great."

"I purchased these water alarms after my hot water tank leaked overnight, causing thousands of dollars in damages. I tested them by using a small amount of water and yes, it did alarm. Very satisfied with my purchase and definitely would recommend these water alarms. They make perfect, inexpensive gifts too."
