Retailer reviews
Summarized retailer review data when available.
Good choice
Very nice LEGO Ideas building set with the theme of space and space travel! It's fun to build and to display in the bookcase or on another place. The various possibilities of setting it up or hanging it, together or separately, are also very appealing. And with the familiar LEGO quality, it is very well fitting and perfectly finished. It's great that LEGO is open to ideas from employees.
Good delivery, in a separate box from BOL (so that the LEGO packaging remains intact)
Very nice LEGO set. Looks perfect in the living room.
