Space Rover Explorer Reviews
Rebrickable
“I love this model. There is so much going on. There are a lot of little details, and different angles. There is not a simple straight wall or roof part to find. This is a great set. There are not many new parts or recolors, but that also helps the price. Just 7.8 cents/part... More is a nice deal, you get 3 models, and there is plenty of MOC potential.”

Tips&Bricks
“Although we've had plenty of space sets over the years, this Creator sets has a lot of great elements. It features techniques such as suspension on the wheels and an opening hatch to name just a few. The alternate builds are fun and very different from the base models, with... More a lot more of the pieces used in the space base compared to the other 2 new creator sets.”
