Looks ok, it still retains the design of the iPhone, so you can show it off. But it does make the phone look a little bulky. So unless you're a fanaticon protecting your phone and yet still want to show of its design and not "hide" it as with other cases out there.. than it would be perfect.
I purchased this case about 3 weeks ago and it's great. I was looking for a case that wasn't bulky and still protects the screen. I like cases that show off the iPhone, but still protect every part of it. It's a very innovative case. I definitely recommend.
