It took me a significant effort to insert my Kindle HDX 7 in this case. The compartment for the Kindle is almost too small. It took so much effort, I was concerned the Kindle might get damaged. It did not.
Both the Kindle Fire HDX 7" and 8.9" were designed so that the mini-USB charging cable inserts at a slight angle toward the Kindle screen. This may have been done to allow the units to be charged resting on their backs without cable strain. However, when inserted in this case, where extra clearance for the power connector is not provided, the cable brushes against the case when plugged in. Whether this will lead to future issues with the female plug in the Kindle, only time will tell.
The support arm for this case is relatively unstable, and touching the screen, even gently, frequently results in the unit collapsing.
Use of this case requires two charging cables, one for the Kindle and one for the keyboard.
The cutouts are all in the appropriate places including the one for the front facing camera, although perhaps a little too tight for the power connector.
Bottom line: Except for the non-trivial issues mentioned above, this case does its job and protects the Kindle in the process. It provides a working keyboard, converting the Kindle into an an easy to use portable computer with almost desktop-like capabilities. It is also attractive. However, it is not correct to say, as the description does, that this is a "leather case". It is polyurethane (PU) and not leather. PU leather is not leather at all! This term, perhaps coined by vendors, may suggest to some that a non-leather item is some form of leather, even though it is not.
A key issue to consider before buying is that it would be quite difficult to remove the Kindle (once inserted) e.g., for temporary use in another case,such as when the keyboard is not needed, or it is desired to use the reader in a portrait orientation. Repeated insertion and removal of the Kindle from this case might, it seems to me, result in damage to the Kindle.
