“I wouldn't want to sell it for any price at this time. If you see it for a cheap price, you shouldn't hesitate to buy it. The 6990 Monorail Transport System includes special elements: the monorail itself, the dark trans-blue windows, the monorailtrack and so on. It has nice... More figures and vehicles, the bases are build futuristic and just the way they had to be. This set offers so much to a LEGO Space fan.”

“This set's main colors are grey, blue, and black, with blue windows and bright yellow highlights. The models are two monorail cars, one med-sized trailer, the control unit for the trailer, and two large bases. The box suggests several Monorail trains and bases, and several... More large and small spacecraft.”

“A working electric cogwheel monorail! There’s so much going on here. I love the larger base with the two transparent blue quarter domes that move. Two bases, a monorail with vertical ramps, cargo crates, loader vehicle, five astronauts, a small scooter, etc.”
