(I work for a contractor and bought it for them through one of our suppliers. Unsure of what other parts that you need with it, FIL direct wired it, he didn't use a plug).
We have it under our cabinets in our kitchen. If you don't have a lip to hide it, you do see the individual lights. Since ours are under cabinet, the only time we actually see them are if we are sitting at the island, so it isn't too bad, but it does look a bit like disco lighting to me.
