Query: Terrible product. It lasted a day

The idea was good but the execution was bad. This soft case is designed to protect the iriver from shocks as well as dirt. The reality is that the rubbery surface drags on everything it comes into contact with including hands and clothing. During the first day of use the material caught and tore across the back. Even if it hadn't torn I would have discontinued using it because of the texture catching every single surface it touched.If you are going to leave the iriver on a table, this item might come in handy. Using it in any sort of mobile way will surely cause you more headaches than it is worth.
