I have an iPhone in an Otterbox, which is a pretty bulky case, and it all fits in this mount with ease. My phone then can rotate, putting the screen in landscape or portrait viewing which is great for the GPS features of the phone, etc. The window suction cup hasn't let go of the windshield yet. The only thing I wish was better was how much the phone shakes on the goose neck if the road is not smooth. But, this is something I expected when I was buying it. Overall, it does exactly what I hoped it would do!
I thought the retractable cord would be convenient. It is not, I returned it the next day. Technically it "worked", if the cord moves at all the sound cuts out. Instead, I am just using a standard jack and have had no problems. Don't waste the energy on this product.
