Sonoff water leak sensor: with sensing wire

Zigbee water leak sensor have been around, and when I was told that Sonoff is sending me one, I assume it would be a branded OEM unit, but this sensor is truly special, as it comes with a sensor wire, and can detect water anywhere on that wire. Allowing you to detect leakage, or water intrusion along a 2m (6.5ft) long line.
