Easy to install and works perfectly. The large volume knob is smooth as silk. As for the durability of the product, I'm not sure yet. It will take a year to install the same. I like it so far very, very much. Already connected for a week (01/20/2016). Rating update: 06/26/2016 Audio Switch keeps turning off. You need to unplug the cable from the headphone mount and plug it back in. It's annoying and I don't know how to solve it. Remove two stars and the words "WORKS PERFECTLY" from the original review!
