"This was a great model to build. It had the right amount of gears and motion parts to keep you on your toes. I like to combination of yellow, blue and black pieces. Very realistic. Upon completion, my grandchildren ( and me) enjoyed playing with it. I brought out my other construction Technic models so we could all enjoy the moment. I bought a second model to either have 2 forklifts and to build the tow truck."
