Given that this set was not cheap, it was disappointing to find how small the vehicles were. The largest one would fit into the palm of my hand and the smallest could be hidden beneath a 10p piece. The construction was OK, but one of the rockets is supposed to be launchable from the space station - pretty poor mechanism that has never worked properly.
Our son (aged 5) had been desperate for some Thunderbirds vehicles, but has barely played with these, mostly because they are just so much smaller than we expected.
A lot of money for not a lot of toy....
