I just got this in the mail yesterday, spent a couple hours Transforming it back and forth last night, and this is absolutely my favorite Masterpiece figure to date. It has a complex Transformation, but both the robot and alt modes look beautiful.
It's perfectly scaled with the MP 10 Prime, which is both a plus and a minus honestly. I love when my figures are in a shared scale. It just hits all the right chords for me, but he's small as a result. Again, I don't mind that, but the price tag for it seems a bit much. That being said, I'd 100% buy it again.
