"Had a great time building this set with my girlfriend. The nature of the Saturn V means it's a perfect set to build with friends or family as you can split the bags between you and build the seperate modules without needing to trip over each other all the time.
Difficulty was just about right for a relatively novice pair of adult builders, it took us about 5 hours between us so I would guess about 10 hours for one person. There were some interesting building techniques as part of the assembly too which we thought were really clever. Nothing too complicated to get frustrating though...the whole process was pretty smooth and just generally enjoyabe.
Really impressed with the overall look and sturdiness of the finished model. You can never get bored having it on display as there's endless positions you can put it in, either fully assembled or with the seperate modules (although having it stood upright in its 1 meter high awesomeness is by far my favourite). Lunar module and landing craft are both nice little finishing touches, and help to give the size of the rocket a nice sense of perspective (i.e. it's enormous!).
I would absolutely recommend this kit to anybody who is even the slightest bit tempted by it, and I can only hope we see more sets with the NASA theme."
