The Strip works fine! I've got a strip marked with 12V GRB. It runs Warm White at rail B, as described., But Cold White runs at rail G, not on rail R, as described. That's no problem. But the strip is bared. The description says it is covered with clear silicone, not bared. I wanted to use it in a bathroom. Now I have to cover it by myself. So only 4 stars.
