I think the case is a piece of thick rubber junk!
It feels three times worse than a zagg back cover, thick plastic crap!
Rushed into production to be able to sell on launch day. I actually did not even notice it was missing the mic hole so thanks for that! I'll cut a hole in it right away!
Having said that I think it is a good interim case till the feather or another better quality case is released.
It does not work well with the smart cover at all, magnets are only barely keep it attached. I mean it does attach but certainly not well.
So to over comes this is a very easy process, just slice the side off the left hand panel enough so the magnets do attach properly. I found removing this section did not have any real impact on the rest of the covers ability to remain attach to the ipad. So once doing this it worked fine, staying attached as hough it was a completely naked ipad
I actually paid a bit more but did not feel like this was any long term solution to protecting the back of my unit so decided it was expendable if my arts and crafts project did not work out.
