Here is my quick summary:
I have the ZooGue case and the PDair case. I like them both. I will be sending one of them back, but I enjoy the look and feel of the PDair. I enjoy the sturdy function of the ZooGue case/stand. I don't care for the ZooGue velcro look, but it works. When the PDair is used as a stand it is sturdy, but not as much as the ZooGue case. If I drop them, I think they both will protect. I like the magnet closing of the PDair.
I fully recommend the ZooGue Case. I have not taken it off once since I received it nor have I thought about trying any other case as well.
