I have been using the ZooGue case for quite a while now.

Mine is warping a little on the flat part of the case that is the part that would be resting on a desk when you're using the case in landscape typing mode.

It's not that hard to bend back, and I am not dissatisfied with it.

When the case is closed, the iPad is still fully protected and the minor warping does not impede the use or the looks.

If I were asked to make a recommendation, I would suggest that in future iterations of the case you might consider using a more resilient material under the leather of that part of the case.
