Great review, and on point. I love my UT Challenger, it fits in beautifully with the other MPMs on the shelf. The design and engineering is some of the best I've seen in a figure, particularly a third party. As you say, the transformation is a joy, the flame pinstriping is well done and overall they nailed this one.

The images presented before release really sold this one for me, I was interested at the prototype stage with its streamlined design, particularly the lack of truck kibble backpack. Once the colour images came out it was an instant sell.

I highly recommend this figure if you're interested in a TLK Optimus.
