I also quite like the mould. Yeah, it is tricky/fiddly, but that's to be expected considering that HasTak have engineered a toy based on a comic/cartoon model that completely:
a. changed the proportion of the original core robot (i.e. raised shoulders and head)
b. ignored the trailer portion, i.e. when transforming to robot mode the trailer essentially disappears (except for this very brief moment (blink and you'd miss it) )

Toy designers obviously can't ignore laws of reality and make half the toy vanish into thin air. In order to make the robot mode resemble the G1 Marvel/Sunbow model they could either:
1: give the toy a detachable platform similar to the G1 toys - as we saw with BotCon Timelines Ratchet and Ironhide, or...
2: incorporate all that vehicle kibble into the robot mode, which is what they chose to do with Universe/Henkei Ironhide and Ratchet

And don't forget that the toy needs to be Deluxe class which restricts the size and engineering (as it has to conform to the Deluxe price point). So considering that it's a fairly ambitious endeavour that has substantial inherent challenges I think the moulds a fairly well designed. My only criticism is how the heads are fixed staring down. Other than that I quite like them.

Comparison between G1 and Henkeis; G1 had half their vehicle form as detachable platforms whereas Henkei incorporates the entire vehicle into the robot mode


BotCon Timelines Ironhide: more simpler and less kibble-laden robot form (repaint/retool of Energon Tow-Line), but about half the vehicle form detaches as a platform (click on image to see view BC Ratchet w/ platform)
