Overcoming problems and problem solving are definitely part of any learning experience, but in my humble opinion a starter kit isn't the place for that. A decent starter kit should work, full stop - components should fit and illustrations should be accurate. If the instructions are out of date, add a supplementary 'update' booklet!Overlooking this, sure, the starter kit is a good introduction - I've definitely learned a lot.
But spending hours and hours, over about half the projects, wondering why completely correct circuits and sketches didn't work only to discover it was the bad breadboard design didn't add anything whatsoever. Once I bought a new breadboard all the circuits worked very quickly... much more encouraging and exciting to a beginner than stuff that doesn't work!
