so after debating and waiting a while i decided to get one of these with some other purchases on ebay. i seem to have a bad QC version which is annoying. I've watched a couple of videos and I don't think it is the KO version but with these it is very hard to tell it seems.
My issues are that the Decepticon logo tampograph on Rumble is off-centre and his left hand and part of the arm seem to be perhaps painted shut or something. I can't flick out the hand and I can't move it at the elbow joint at all not matter how hard i try. There is definitely some sloppy or extra silver paint in those areas. FFFFUUUUUUUUUUUU
One thing that might be interesting is that it seems to be a Hasbro China version or something. On the box there is a white sticker or label covering part of the box with chinese writing, phone numbers and hasbro.com.cn web link. I have a separate Chinese instruction sheet as well as the Japanese one.
I will contact the seller about options.
