In short, it's a pretty solid case that'll protect the back and sides from scratches, but leaves the screen exposed to the elements. However, there's one thing that DLO overlooked when designing this case.
The one, pretty important thing: the buttons. Because the "back" and "play" buttons on the Zune are actual buttons, you're going to need to be able to actually push them down. The way the case is designed, the two buttons are pretty hard to press with all the raised rubber in the way. Unless you use your nails or have small fingers, this may be a problem.
That aside, the sides have raised grips that you'd find on the bottom of shoes or showers, which makes it even harder to lose your grip, no matter what you did before.
The top and bottom have holes cut out for the headphones and Zune dock connector, so you're set there.
For $19, this is a pretty decent quality case—save for the button problems. If you're looking for more of a luxurious feel, we've got a hands-on with some leather ones tomorrow.
