The bags and mounting brackets seem to be high quality. But OMG, whomever the engineer that came up with how this is installed should go back to school or find another career. The design makes it very difficult. It is very obvious that he has never been in the field installing anything. The instructions come with torque specs but it is not possible to use a torque wrench. Not for your typical shade tree mechanic to install but could be if the preteen that designed the mounting hardware learned a little, a LOT, more. Other than that, I'm good.
