Brilliant Lego! (also helped I got it £10 cheaper off Amazon than from anywhere else!)
Bought this for my son's 4th birthday - he loved it, we had to put it together there and then as soon as he opened it. Pretty easy to put together as with all Lego instruction books - easy to follow and piece together as you go. Took around 45 mins with my son lending a helping hand, passing me the pieces etc and playing with it half built. Comes with some great little minifigures - A Pilot, Passenger and Airport Worker. Along with the plane as per the picture you get a airport vehicle, a suitcase and the radio/signal tower? (not sure of the precise name but it's that thing on a stick coloured red & white that moves!)
The top of the plane comes away in two parts so you can put the passengers in, the front cockpit also comes away so you can put the pilot in, easy enough for my son to do on his own without the plane dropping to pieces so keeps him very happy that he "can do it on his own" as he tells me.
No faults to mention with this piece of Lego, we've even bought some extra lights direct from Lego 'pick a brick' section and my son has now covered the top of his plane in lights to make it so it can "see in the dark when it's landing". I'd actually give this product more than 5*'s if you could. My son's love's playing with it now and I'm sure he'll get loads of use out of it in the future.
