I had ths product as a young lad and couldn't resist buying it for my six year old son to add to his D-Day Gift Set. As a model in itself, it is very simple and basic, which is good for youngsters as they can construct and paint it withsome ease. The boats also provide very good playability as they can be used with figures and other products in the Airfix range.
Possible downsides to this product include the slight errors that seem to have been made in the positioning of the holes into which the barriers are fitted: they only line up after considerable fiddling, which may be a problem if you're leaving your children to put this model together. Also, in absolute terms, £8 on Amazon is a bit on the expensive side for a model that comprises only eight pieces, plus the boats.
That said, the nostalgia value and the portability of this product to a variety of dioramas/scenes.layouts means that it's well worth a purchase.
