It fits the S9 perfectly. Very nice quality and worth the extra cost for workmanship. Leather is of excellent quality. Only complaint an is minor to me. You have to remove the S9 from the case to charge or connect to USB cable. IMO this would be a pain to remove the port cover even if it was open. I've seen others that have the port open and they look like they would last because the only other place to secure the bottom of the device from falling out would be the phone jack opening. I prefer the trade-off to having the USB port covered. So I like this design better. Cowon should have put the port on the side and a perfect case could have been possible. The device fits snuggly, but is not difficult to remove. I've had mine for about 3 months. At this point, there is a minor tear in the interior cloth next to the exterior edge of the volume switch. The leather and the stitching are holding there so, it's fine to me. While some of the buttons are covered, they can be pushed through the leather to access the commands.
