You could say Silkroad is still in "Beta Stages" at the moment, it's still being developed thus the feedback system isn't in place just yet. But you can go here, Rumor Mill - http://silkroad5v7dywlc.onion/index.php?board=15.0 This forum has threads with reviews of various vendors, if you don't see the vendor you are thinking of ordering from then you can make a thread and see if anyone has any experiences with them!
