most frustrating toy

Official status in our household is that the decepticon transformer Demolisher is the most frustrating toy of Christmas, 'suitable for age 5 up although some adult supervision may be needed for younger children' lol over an hour to get it from one state to the other, partially because our 6 year old had a go himself first. They are actually really well thought out, rather complex and just a little too frustrating for my old head.
