Reviews — from Brickset owners
This is by far one of the best sets to build, take apart, and build again, if that's your example of fun with LEGO. Makes a great display piece, but not a great product for kids. This is definitely a great starting point for up and coming AFOL's. A bit pricey, but that's what you get for quality sets like these.
