Pretty good
The only issue with it is that it took quite a while to learn how to use CORRECTLY. I could only switch between one or two songs, but then realized if I highlighted all of the songs in Itunes, I could go through all of my songs without a problem. I also eventually figured out where exactly to put my finger so that the camera would see it. So, in summary, it takes A LOT of getting used to, but can be learned and used easily.
