These worked very well. Seem well made and are operating with no issues. My only minor comment is that pin numbering is either faded or sometimes not readible. So one just has to take care that the proper wires are plugged into the proper pins. When working with this stuff and all the wires it is easy to become disoriented, so I find I check wires and locations frequently to make sure I am making the proper connection. Some of the relays we better marked than others. Cosmetic yes, just needed to take a bit of extra caution. Functionality and connecting all very good. Really a super value. I just installed 4 in a project I have recently completed. I will update this review in a few months to provided additional details.
