Hejnar 10″ Macro Focusing Rail MS5P-10-KS has a high price of 355 USD but its build quality is far lower than products made by Kirk Photo and Really Right Stuff (RRS), and even is not at the same level with Leofoto.
I am very disappointed with the build quality of Macro Focusing Rail MS5P-10-KS, and I don’t recommend anyone to buy products of Hejnar photo at all, especially the products with any movable or rotatable mechnism.
