How accurate are the guides online which show the differences between knock off dinobots and real ones?
Like I'm looking at this one on ebay and while the arms look ok compared to this-


the feet don't look ok compared to this-


Should I just ignore any Grimlocks that have the double marks on the feet to be safe, or are there some legit ones with the double markings?
I actually see a few that look 99% legit (like this one) the only thing that seems off is they have the two spots on the front claws (check the second picture on the second auction) as compared to one on each claw in the comparison picture.
