Looks mounted quite good, although the Tiger logo does not really stand really strong. I can not say anything yet, have not yet installed it long and thus remains to be seen over the durability. The price / performance ratio? Well ... for that price I expect definitely reasonable screws! The included are an annoyance and not suitable for installation. Because of the Spacer I can not mount for mounting above, even without the discs the bolts are too short. I must here therefore use the original screws, which are also higher quality. I can down because of the spacers, neither the original nor use the supplied screws. All attempts to accomplish this so degenerated in fumbling without success, it is difficult enough to make the holes with the screw thread in compliance. So get the same for the middle screw 2 is about 10 mm long. I do not know why the supplied necessarily have to be silver, black would be more appropriate here ... for mounting at the bottom I can the original screw or use the supplied. Due to the good design, the relatively stable sheet and fast delivery I forgive with benevolence 4 stars.
