runs great. powers both the LED and LED bulb. nice display piece to add to a collection.
Amazing little machine. Very nicely crafted. My son got it to run within minutes. Created with excellent attention to detail, seems very rugged. When not playing, it is a good display in the show case in the family room. When friends are intrigued, you light it up to show what it is worth. If you can get your children to understand the physics behind its functioning and develop love for machines, they will surely turn out to be good engineers.
