To my mind, the part is a very expensive Jakob. At first ride in this spring, the first coffee in Tequila Drive, I had to take note that the zipper of the bag, so the most important design element at all, without particular pressure, just by normal wear proper handling, opened. Luckily I did not lose my smartphone on one of the bumpy roads in Brandenburg. While you get a lot of parts for relatively little money. But what good is the amount? My delivery ended up in the garbage.
