The overall look of these compared to the original are leaps and bounds better, the sheer size makes the figure looks a lot more menacing

You're not prepared for how much larger these wings are. They dwarf the original wings that came with Pumpkin/Unicron.

Pros:
-Ginormous in ring mode
-Adds to his regal look
-Easy to assemble

Cons:
-Too ginormous in some ways, shelf space is difficult for most
-Assembly is required
-No screw caps (bleh)

Final thoughts:
Is it worth it? Well, if you've spent the asking price of Pumpkin to begin with, what's another $40, at this point? So, yes and no. The space issue will be a problem for a lot of collectors as this ring is on the redonkulous side.

The assembly is easy enough but requires a lot of force to get the pegs to slide in. (This is meant to be permanent, so you really have to push. I have marks on my hands from pushing it all together.)

The lack of screw caps is a glaring issue and makes him look incredibly uneven. You're made very well aware that this is two of the same wing, just one facing the other way. Cuts costs and saves you money but I think they could've thrown some caps in. Seriously.

The new joints and articulation in the wings is quite impressive. It forms the ring and comes apart with ease, no more worrying about whether or not you'll break the tabs on the original ring.

I gotta be honest, while pricey for what it is, it does look good and it's well made. If you have Pumpkin, you should get these.
