I have this shell and there is a sizable gap between the case and iPad where the smart cover attaches. It's several mm wide and dust/dirt can and will get trapped scratching the iPad. The case does not sit flush on all sides only the top. If you set the iPad down on the table face down (screen against the table) and push down on the shell there is a few mm gap across most of the back shell. This is a major issue for those who are concerned about getting dust trapped in the back and scratching the iPad. I've contacted Marware about this issue and have yet to hear back. Here is a shot of the smart cover side of this case. Just got an email response from them: "Hello wgr73, The gap you describe is normal with the new Microshells. It's not a defect. We can replace the case for you, but the device does not fit in flush with the case. Please let us now if we can be of further assistance Marware Support"
