I ordered two of these and neither of them functioned. I would not trust these and was very disappointed in the product. The first one, upon opening the case, had leaked it's battery on the inside of the sensor. For the second one, I was able to connect to my smart phone but when I tested it by pouring water on it, it failed to register and signal an alarm. I am returning them.

Unfortunately, this item never worked. After downloading the app and wasting lots of time- the device would never work. It is poorly designed and built. The battery will not even stay in the clips. Don’t waste your money and your time on this product.
