Takara did an outstanding job retooling the Powermaster Prime mold into the spitting image of Super Ginrai.

As for the big question, yes, these feet are actually quite stable when transformed correctly (don't attempt to rock the feet front-to-back, as the weight of the figure is intended to travel all the way down the foot), and the added articulation helps with a figure this beefy.

Plastic colors, paint and transformation feel great, with a scant few exceptions that may or may not affect your copy.

First, I know that the RIGHT hip on my copy is slightly mis-assembled, as it is pinned slightly off center from the ratchet disc, causing uneven movement and a lack of clicks past a certain point. This is also evident when going into vehicle mode, as one side doesn't play AS NICELY with putting the trailer sides together (though it should be noted that both sides are relatively easy).

Secondly, the red flap on the top of the cab likes to fly off even when exercising extreme caution opening the front of the cab to flip Ginrai's head up and down. Not sure if this is a tolerance issue or inherent in the design, but it's annoying.
