Finally got this guy yesterday (fishpond.com.au order arrived) and thought I'd post a few thoughts.

I'd start with the negatives as they seem to outweigh the positives (at least for me) and it kinda ruins the whole thing for me.

Cons:
- very top heavy (due to sound box and batteries)
- crap feet design (fairly unstable)
- difficult to pose (due to first two cons)
- annoying sound gimmicks (have removed batteries on mine)
- loose grip on weapons (shield flops around)
- pinkish red colour (would have looked nicer as a darker red/magenta colour)

Pros:
+ displays relatively nicely (has shelf presence)
+ nice transformation sequence (a bit fiddly, but ok)

Of the three DOTM toys I've purchased so far, I had such high hopes and expectations for this guy, but I actually enjoy DOTM Deluxe Starscream more.

And that's really all I have to say about this guy... I'm totally disappointed in him - wished I left him MISB instead of cracking him open to be honest.
