This is one of the easiest and versitile lighting systems I have ever seen. I'm using it on an N scale train layout my dad is working on and we bought a house that was prewired with this system and we weren't familiar so I did some research. It is easy to use with the plugs and does the job perfect. I was so impressed when I got it, I then ordered a port sharing device, extension wires, another light hub, and the expansion hub, with master switch. The dimmer switches are great. I also got a few extra lights, for my N scale houses, street lights, and gooseneck lights. They all hook up with no fuss. My elderly dad was like, "it's about time someone created something so simple that looks so good." Glad we stumbled on this system. He's been waiting for decades.
