That SDCC art/box is very nice but I thought the box I carried home was big enough!
My initial thoughts on the regular Hasbro version:
Big! So big. A bit too big for his legs. It's not really a figure you can pose on the shelf but he's got enough joints to be flexible.
The fake kibble helipad on the robot mode shoulder is a bit odd.
He looks good without stickers, enough textures. I don't miss the chrome. I will add stickers but don't really like the ones with Cybertronian on them.
I love the vehicle mode, it's the space battleship I imagined back in the 90s, but both vehicle and city mode do suffer a little by the very long legs. They look fine in robot mode but stretch out a bit too far when folded out.
I had trouble getting the ramp out the first go, was worried about breaking it because it was so tight.
I like that that the city-to-battle station transformation adds a little more complexity than the G1 version had.
It's a great homage/remake to the original toy, the big toy I always wanted Metroplex to be, and I think for the size quite a reasonable priced figure.
