I finally got around to opening mine last night. I too have the Takara version. I really like the colours and as others have said the robot mode is very solid.
I dig the boombox design, I'm pretty sure I've seen speakers on stereos looking exactly like that with the silver panels protruding over the front.
the 'base' mode is OK. it works better once you have a few more titan masters and their seat weapons plugged into it.
I did also find that several of the titan masters don't quite fit the little pegs. I'm pretty sure the pegs are marginally too big. something that will be tricky to rectify without making them too loose.
I don't mind the helmet design/concept. I just don't get it in this case. especially taking the Takara Titan master into account, it doesn't quite look like blasters face, I'd have much preferred a fixed head that took up the same space that was able to do more than rotate left and right.
