I gave it a 4 simply because the instructions say to use the long bolts when installing. I got it all installed exactly like instructed and they were not snug at all. For those of you out there that had this same problem and spent an extra 30 trying to figure out where you went wrong (JUST USE THE SHORT BOLT INSTEAD) I was so frustrated that I almost sent the whole thing back. Until I found the secret solution.
