The center button of my ipod video was stuck down and sometimes would not click.
That was the first time I had ever even thought about opening up or trying to fix an electronic device, and it went great. The guide was really easy to follow and the tools made it even easier.
The whole procedure was a lot easier than I thought it was going to be. Although the inner parts of an ipod are pretty small, and i've got big fingers, it still went really well. It was kind of hard holding the orange ribbons in place, but once I figured out a way to do it, it was really easy.
