We have many sets of tut tut as our 2.5 years old son is very excited about the stuff. So far, I have always been annoyed that so little is street share it and you can thus connect poorly the sets.
With this set, you now have many more options. For mom and dad even is at also what we must stick the road markings even;)
I think it would be nice if more would just parts here, but my son is happy and that's the main thing. Buy recommendation!
