I purchased one of these cases last week and it arrived on Monday.

The case is made of a hard black plastic material and comes with one screen protector. Note that the screen protector does not have a cutout for the front-facing camera, just for the speaker.

Installation of the included screen protector was extremely easy, as long as you follow the instructions included. The screen protector seems to be of fairly good quality, and you can easily 'smooth out' any bubbles trapped under it. You can peel it back and re-apply it if it doesn't go to well the first time.

The case itself is very good quality. The back piece has a silicone inner liner that provides some additional shock resistance.
The front piece just snaps to the front of the device, and that's about it. All ports and switches are accessible; the micro-usb and earphone jacks have little flaps that open up, while the power/camera/volume buttons have a thinner 'permanent' silicone cover that enables you to use them just fine.
Overall, the case adds maybe 1/8" to the overall thickness of the device, but I can still carry it in my front jeans' pocket without issues.

Some have mentioned the stylus is difficult to get out, and that is true. I don't use the included stylus; I have one of those Fisher Space Pens with the stylus tip, and I love it.
It's a bit pricey (around $20 on Amazon), but the size and weight are nearly perfect, and it's small enough to fit in your pocket without causing any discomfort.

I hope this is useful for some of you thinking about purchasing this case.
