>>9695939Box mode locks together tightly, and transformation is in the intermediate range of difficulty - the hardest part about it (which the instructions don't really make clear from the angle it's shown at) is that the yellow segment of his thorax with his head and wings on it has to rotate separately from the black part underneath with the legs. He ends up nice and snug, but the one part that concerns me is that those little grey tabs on the top of his box form in pic related snap into some pegs on his wings, which are made of clear plastic. They seem sturdy enough (for now), but I've heard many horror stories about clear plastic breaking over time. Sadly, you HAVE to fold the tabs onto those pegs to get him to fit in his box charger, so it's unavoidable - I recommend using caution just to be safe here.
