My son pleaded for this toy; waited for Christmas, waited for the marvel of the conversion chamber. What a load of rubbish. It is nothing like as slick as Lego - the instructions were not exactly crystal-clear and once assembled, it fell apart so frequently that my son was reduced to tears of frustration.He has never been reduced to tears by a toy before. My husband ended up gluing the thing together so that it could be played with. We expected better quality from a franchise of this association, but be warned BBC brand, my son saw another toy in the range, but then said, 'there's no point in getting that - the stuff isn't very good'.
You can't talk kids out of a toy they have their hearts set on, but I can't in all honesty recommend it.
