when I get the item I though it could be easy to set it up , but I be wrong . the instruction be so bad that it include only one paper with no picture , tool be not number or name . I get the picture from the internet , but it be still difficult to figure out which screw be go in which hole . the screw be too big and too small ... I have hard time set it up , it take I almost three -lrb- 3 -rrb- hour to set it up . but the bumbell be great . and one star be because i cant put lower then that ...
