I think kids would find it much harder to use the waist gear considering how tight it is and how finding a right place to set your other hand to hold the figure in place while your other hand turns the gear can be quite frustrating (for me at least)
It’s difficult but I have to say that I like the 2015 function better. I have some problems with the 2016 function, those being:
the friction level and squeaking varies dramatically from set to set
it’s a lazy design- it only uses 2 or three pieces when the 2015 function used so much more pieces
the two main pieces CAN NOT be taken apart- at least to my knowledge
it wears away over time and through use- I can see the dust from the plastic wareing away building up in the various holes on the black torso piece. It probably will not last for a long amount of time if used constantly.
it squeaks annoyingly!
That’s why I don’t like the 2016 function. It just doesn’t feel like the quality I expect from a Lego product. It makes for some neat poses though
Oh, come on, the only thing it does it make their arms go up and down. It doesn’t matter how young you are, how can that possibly be fun for more than five minutes?
On the other hand, I got my first Toa Mata when I was 11, so what do I know?
