I've had this otterbox defender on my iPad for a couple years now, Adrian. It's impossible to tell it from new and the iPad looks like it was made yesterday.
The big plus is that the back snaps off and covers the screen. Whenever I travel or pack it in a bag, that keeps the screen from getting squished. Even when it's getting tossed around in my laptop bag or suitcase, or packed in the back of the car.
This thing has taken a huge number of scary hits, even dropped face down a number of times and the kids have stomped on it. It's an amazing case.
It's bulky, but that makes it easy for me to handle.
I have the defender on my iPhone, too. I can't even hold it without a case, it slides right out of my hand while I'm talking on it.
