I'm kinda torn on this. Little gray splotch aside, that altmode is basically Essence of Cliffjumper. Similar vibe to seeing the Retro Brawn, gorgeous forest green and black square on hood and all. And this mold at least holds the rear chunk of the car to the body via a folding arm, like the Earthrise/Buzzworthy one should have gotten, and the roof chest in robot mode is the right way round. Lots of little pluses for this mold; I've yet to get Bee because of the headsculpt, but car front aside, I love how Bumper turned out.
But despite the second try, the robot mode still lacks the show model's little chest spoiler (they've never really gotten this in the remakes because of the transformation), and the colors are off compared to the Buzzworthy one, which I already have.
