Bought this case shortly after getting my new Sony NWZ-A815. Very pleased with it, covers all the right areas well. Has a nice Walkman logo on the front, and a Sony one on the back. As mentioned, the bottom of the player is exposed but this isn't that much of a big deal as the WM-Port is covered by the slider in the player when not in use, and the case has a tight grip on the Walkman, so there is little chance of it falling out. Sony likes to insult our intelligence with the instructions on this case though, I quote this from the back of the packaging:
"To insert the Walkman into the case, slide it with the screen facing upwards all the way into the case"
"To remove the Walkman from the case, press here (arrow pointing to Walkman)
Otherwise, it's fantastic, great buy and essential for your new precious player.
