Works exactly as it should. Some users experience crashes, probably due to incorrect application of the sensors. These are SENSORS, not switches. They should only be used in pilot mode (low or no current load) and connected to a relay that can control the power of the load. In the case of inductive loads such as small motors, starting currents can be up to 8 times the specified operating current. "Unsuccessful closing" is a sure sign of welded contacts due to excessive current. These are magnetic reed switches activated by a levitating magnet in a waterproof case. If used properly, they should last indefinitely. These facts should be made clearer in the announcements.
