All about this set

Inspire kids aged 8+ to adventure into outer space with the LEGO® Technic™ Surface Space Loader LT78 (42178) set. It makes a great gift for boys and girls who love space toys and construction vehicles. This space exploration toy is packed with realistic details inspired by cutting-edge space engineering designs. Kids can steer the loader and raise the cabin before using the crane to pick up and move the cargo. This set also features a special space air-lock element so kids can connect other compatible space LEGO sets (sold separately) for even more space adventures. The LEGO Builder app will guide your youngster on an intuitive building adventure, letting them zoom in and rotate models in 3D, save sets and track their progress.

Very cool set. It’s amazing that it is actually functional. You can steer the the car with the steering wheel, it actually turns the wheels. There is a part that you twist to raise or lower the car. It does take a while to assemble, but the directions are easily followed for older kids or with assistance. The age range is pretty accurate as this seems to be more of a car that you would want to display or carefully play with. I would not recommend to play roughly with this car. It’s a space car so there is a lot of attention to detail within the car as it comes with “specimens” to test and detectors. I would recommend this set to others. I received this in exchange for my honest review.
