I got mine yesterday and I'm very disappointed. The top and bottom are saggy and they barely come over the front glass of the iPhone. When I press the home button, the bottom moves down! And it's not like I have a giant thumb.
You can see in this picture there's a give at the bottom :
The inner shell (kind of silicone) is a dust magnet. The buttons are impossible to press and the finish quality is horrible : on my case, on top, there's a thin, irregular, line of silicone hanging out. It doesn't look good...
It's hard to see in this picture.
At least it feels great in the hand and it seems to be quite protective. But still, I'm disappointed!
