I saw the Mand Labs electronics kit and books. Was thoroughly impressed with the professional design and the thoughtfully chosen components. The kits came with two well-prepared books, which listed a large number of experiments for students to try out. As expected, the level of the experiments keeps getting more involved as the student progresses. Towards the end, I remember seeing circuits built using multiple transistors. The website also has a number of videos to go along. I think this kit, along with the material in the books and the website, should serve as a self-guided dive into the world of electronics for anybody who has an interest to learn. It will also encourage the student to try out their own ideas. One thing that stands out about Mand's is that it does not shy away from getting into the details. There are vivid diagrams that highlight the currents/voltages etc. This was in fact refreshing in times where increasingly we see a tendency to 'abstract out' from the inner details.
