I would have given 5 starts if the instructions were a bit clear and parts were properly labelled. Had to do some guess work. DO NOT use a torque wrench on the nuts and bolts as you will strip them easily. hand tighten all nuts. Do not strictly follow the instructions and only tighten the nuts at the end because some steps will require you to unscrew the bolts from the previous steps. I wish all this was written down in the instructions which are only a series of faint diagrams.
