I am very happy with this product and the quick delivery. The communication also was very good. These controllers work on multipool led lights and different types, so they are very versatile. I first needed a replacement for one that had malfunctioned and that's when I found I could use it on other lights. I now don't buy complete set from expensive outlets. I can just buy as required and build on the lighting system I already have. I have saved this seller to my favorites as they have a good range of products.
