First off this adapter is smaller than i had expected, I have a Sony Clock Radio dock and it works perfect. I also have my Iphone in an Otterbox Defender Case and at first I thought it didn't fit, but all I had to do was give alitte pressure and the adapter slid right it, it is kind of nice because the otterbox holds the adapter in very snug and I feel it is more secure, I am very please with my purchase.
What's great about it: Works Perfect
What's not so great: It doesn't work with every case.
