Got this guy over the weekend and I'm thoroughly impressed.
I'm trying to move away from MPs and focus more on CHUG and this guy definitely is a nice substitute for the MP - in some ways it's actually better.
After multiple transformations I'm still finding it hard to put it down. It's on the more complex side but still very intuitive and fun.

My only issues with it are:
1. The arms don't have any friction when they swing out to the sides so tend to drop back down. Forward and backward motions are ratcheted though.
2. There is barely any ground clearance in vehicle mode.
3. The missiles only attach to the sides of the vehicle trailer and not the very front like the G1 toy.

Admittedly, 2 and 3 are nitpicks. It still rolls fine without scraping and as it's a Studio Series toy only screen accuracy is required, but it would've been nice to have the option.
I think they should have done better in regards to the arms though.

Otherwise, a very enjoyable figure as I said. IMHO it is the second best commander class we've had after Jetfire.
Highly recommended!
