Now something more serious: It took the part of a stand at a podium, which is why we are (as students) do not often against threats with a Bobby-Car. For durability, we can not say anything, but as a prop on a table it was great. The most annoying thing was the screw on the battery compartment. Sure that makes sense for children to feed no batteries, but to get at the university a screwdriver was unexpectedly complicated. The same applies to batteries, which were also not included.
When the light arrived, we were first impressed with the automatic circuit that really comes close to that of a real traffic light.
