Mine came in the mail yesterday and I put it on when I got home lastnght.
Overall, I would recommend it, but I do have several issues.
The plastic that covers the screen is my main issue. Definitely reflective, and hampers reading somewhat. I may get used to it with time, we'll see. I would have preferred to see a non reflective material, such as a clear silicone, but such is not the case.

EDIT: After 24 hours of use, I'm getting used to it.
The hole for the power switch at the top gives just enough room to get your fingernail in there and slide it. It would be nice to have a little more room to the left.
Mine may be unique, but the silicone for the power switch will not stay in the anchor hole. It pushes in just fine to create a water seal but is not actually attached to the case. EDIT: My wife, who has much better eyesight and is much more dexterious, was able to fix this for me.
Typing on the keyboard is easy, which is huge for me.
Overall, a good product which I have no reservations about its ability to do its job: protect my Kindle.
