"Not only is the build fun, but the play factor is just as fun with all of the motors and functions of the final product. The hubs connect well, and have only had minors issues with the tracks slipping while driving on carpet"
"Acquired 2 with the Excavator, have had no issues.. all of the motors and sensors work as they should. I like how the Hub turns off as a brief time of disconnection or not in use in order to save battery power."
"The fun of building Legos are the building process to a beautiful design. Some phases were challenging, but this is the fun of it. I can clearly understand why the build is 18+. The green color is amazing for this model, and everything fits and snaps together beautifully and is very durable!"
