They do not smell of genuine leather, but it is ;-) consisted of real leather (lighter test.
The 5230 fits tightly in the bag and can with an open "door" do not fall out. You can make calls with the flip closed. Well so, otherwise it would be quite fumbling.
Too bad that the bag to closed state makes quite thick (25mm +). The Velcro adds a few mm. Here a magnetic clasp would be beneficial and the "ratchet" when opening also could be avoided.
In the case of the data port is not accessible. If you want to connect via the 5230 cable to the PC, you have to take it out of your pocket. Not dramatically, but .....
The upper and lower right corner of 5230 is not protected by the bag in the fall. Is it one of these corners, the case is taken.
Otherwise, the case is handled properly.
