Got mine combined yesterday, and it was very nice and a lot sturdier than I had expected for such a huge figure. Aside from Hook coming apart a little while posing/playing, Devastator is like a single solid toy. Hasbro & TakaraTomy have done well on this set.
I only needed to look at the back of the box a few times to see how each Constructicon needed to look for their parts to join together.
It is imposing and impressive... and If I were to vote on a favourite 2015 toy, I don't think I could pick one out of all of the Combiners this year.
(unfortunately this is a bad timing toy, as it is distracting me from processing my BotCon photos and news)
While building it from the feet up... Long Haul on stilts.
With some random toys of different sizes, towering over all of them.
Climbing my Masterpiece shelf to get at the Autobots. (he's actually holding onto the shelving with his hands and feet)
The Autobots about to fire back.
It reminded me of the episode "City of Steel", which had Devastator climbing the Empire State Building like King Kong.
