I bought a child for 6 years-very much like all the working mechanisms. At this age, it is not collected-it is definitely. I collected, he looked, sometimes held. We did it in about an hour. In the kit everything you need. They put even screws with a stock and one spare screed and an insulation tube. The screwdriver is attached. There are no batteries only (AA 2 PCs). As far from the electrical devices, I think that I managed quickly and on Hurray :) Where it is proposed to burn the insulation of the wire, cut it with a knife. That's what Google was trying to translate. The material is raw plywood. I do not know if it will last for a long time, but I'm still pleased with myself. Delivery to Moscow is fast.
The elevator is excellent, the details are quality, it's easy and simple. The order came in less than a month. Thanks seller❤
