I got two of these, one in purple for Blackjack, and one in yellow for a friend who has Rodimus.
The shade of purple used on this is a little bit lighter than the pack in weapon, but still looks excellent being wielded by Blackjack. In fact, I have him dual-wielding right now, using both this piece and the regular weapon.
If you don't want to give Blackjack (or Runabout for that matter) the Rodimus-style "spoiler tips over the shoulders" look, it can also be mounted upside down on his back, making it look more like a backpack or even a glider.
This was my first experience with a product like this and I am very satisfied with my purchase. Thank you!
