2 out of 5 I have already installed and work fine. Very satisfied. Visual inspection revealed no defects. When switched on, the coils all sound the same. I will update if one of them fails or if all 5 are as reliable as their apparent quality shows. I use them to switch LED light strips to run far from the 40 amps they are rated for. They must be operated at less than 50% of their rated power for life. It is worth buying and buying more.
