Interesting, rare and sometimes cheap ebay items.

but now I'm really worried about how legit his products are?

A couple of year ago I purchased quite a few Classicsverse figures from similar sellers. Didn't get any really bad ones, although the out of box Classics G2 Green Tank Megatron felt like crap in my hands.

The real highlights were Classics Ratbat (Cybertron Noisemaze repaint) and Movie/Classics Crankcase (Cybertron Red Alert repaint). Both of which were out of box and of good quality, however it was really odd that Classics Ratbat came with the translucent rubber bands tied around it, and packaged in alt mode - to the best of my knowledge that figure was only ever sold as a 2 pack with Classics Springer (Cybertron Evac repaint), both in packaged in robot mode. There were also very minor errors on Ratbat, like his allegiance feature not working. It leads me to believe these figures were produced from legit Hasbro factories, however perhaps made from the parts of figures that failed QC in some way? Peaugh/Vangelus once boasted buying figures smuggled directly out of Chinese factories prior to official release.
