    Looks great, but doesn’t work too well.
    Awesome looking set, kept me busy for the thanksgiving break. However, the set is lacking behind on power functions. The white “protecting” gears connecting the motor to the gear box kept slipping and I had to replace them with normal 3:1 gears for the thing to run smoothly. The gearbox mechanical designs are also sub-par. The drive train kept skipping gears. However, if you take the time to fix those issues and be a bit creative, it’s a really great set.Oh and forget about scooping up the dirt pieces they provide you. It barely scoops anything up even on a huge pile of Lego.
