"Got this as a father's day present as something me and my 4 year old son could work on in advance of our trip to London.
It's been a great success - it's pretty straightforward to build - too complex for a 4 year old to easily follow the instructions, but easy enough that he can build it with an adult's direction, so works well as an activity to do together.
The model looks very nice, fair amount of detail, and completed looks like a good replication of the real thing. My other son (who is 2) also took great delight in destroying it - but both boys were delighted when they then got the chance to see the real thing.
