I bought this charger bout a month ago and it has worked great so far. This charger cost a little over a quarter of what it would have if I had bought a genuine Apple charger. If this product last at least a year and a half I will consider it a success as that is all the longer that the original charger lasted. The only setback with this unit is, when you charge your Ipod through the computer, the unit quits charging the mp3 player when the computer goes into hibernation. I don't remember the original charger doing that, but I have a wall adapter so I just plug this charger in that and it works great.
