Unstable Quality Bought two sizes 250mm and 350mm. 350mm works great! Came well lubricated from the factory and glides very well with almost no effort. 250 mm are lubricated and almost non-slip. Also, it looks like they are two different brands! One car has the official laser marking on the back and the other has -2 scratched out on the back. The rails themselves also appear to be of a different style. Probably avoid them and buy LDO rails or try Wusongshire.
