I bought 2 of these cables to replace my regular DVI. After installing them on my computers, one had a static buzz (hum) constantly coming and going through both cables. The other was plugged into the audio out plug in port for some reason which also sounded like noise. Since I needed it ASAP or else I would have just returned them. My guess is that they are either defective from the start or very poor quality control. I'm currently using theMediabridge Hi-speed - USB 2.

These are by far the best quality and most durable dog toy I've found. I don't feel like they should be $25, but that's just me.

I picked this one up for my son based on a recommendation from his music teacher. It was awful. The first couple chords were OK, then the rest of it went totally out of tune. So bad that I could barely make anything resembling what I had heard him play. It's not even really possible to figure how badly done because he can't play all the notes. My daughter learned just as badly. We returned it. If you actually want to do something right get yourself any other classical children's music.
