Sometimes, it takes an impact to get the notice. In this case, G-Form has done it well (at least for me) by dropping an iPad from 500ft and surviving it without a scratch.
And by the way, it sleeve also fits the iPad2 with the Smart Cover. Of course, some may argue that it dropped onto a soft ground and they should show the results without the sleeve. In my opinion, I would think that this demo is sufficient enough. Who would drop an iPad from such extreme height. Watch the video.
Here is another video of G-Form iPad Extreme Sleeve being hit by a 12lbs bowling ball. Notice the cracked screen on another rugged casing.
