Have worried for the kitchen to me this device. From the first impression all is well, you even have the choice between grellendem whistling or music. If you switch the power on, there is an advisory does it all, thus far 5Punkte. But. The sensor is fine and easy to attach by suction to smooth surfaces, only then is the sensor height in the unit starts min. 1cm. With its commitment to sensor flat on the floor so the water must be 1cm risen so that it touches the sensor surfaces again. I have the sensor then placed with the sensors down to the ground, until it has been difficult him just to get on the ground because the cable raised him repeatedly but eventually I had it then, the water test, it did not look good, by the surface tension of the water surrounding the water though the transmitter, but does not penetrate really under him making the device only has reported as the sensor is washed away by the water mass. For me, this indicator is recommended only if you want to monitor a well in the water possibly an increase is to be feared, or on the package as an overflow protection for the bathtub. And unfortunately for 2 points deduction because before a water level of 1cm forms in space that is half the house under water.
