Both my children utterly loathed this. As a pianist myself, I had to bite my tongue as their teacher had sworn by it for a long time, but I was aware of other parents indicating that their children (and they themselves) shared my view. Both my children are musical and musically motivated. Both quickly saw through, and tired of, the pretence of 'real' repertoire (the pieces are all concoctions by the Bastiens themselves, of whom there seem to have been a small army), and personally I consider the specious separation of technical exercises and so-called 'repertoire' into different volumes a cynical rip-off, at a level where there can be no substantive difference between the two. You spend bucketloads of money for something that could have been done far more approachably and less repetitiously. For UK buyers the tone, in any case, is Transatlantic, very dated and rather austere. Plenty of alternatives manage to inject a more winning and 'hip' note into the proceedings for children without neglecting the essentials. For my money, this is yet another system that overlooks the crucial importance of instilling confidence at an early stage by making plain that each octave of the keyboard is in effect he same as all the others (something handled admirably by the Harewood/Waterman series, where the young player quickly gets to understand the layout of the whole instrument and to cultivate some agility in this direction, at a basic but useful level). The main Bastien is no longer with us (he died about a couple of years ago) and there will be no more of these, one presumes. I'm sorry to say I don't think anyone will be missing out too much. My comments apply to the whole Bastien range, of which I've had enough vicarious experience for several lifetimes. The material is arid, unimaginative and, in an odd but deeply offputting way, actually very patronising to children. My own, with fairly well-developed critical faculties from growing up in a professionally musical family, quickly bowled out that there's something dubious about material that presumes to stand in for classical composition without explaining why the real thing is unacceptable. They both wanted some decent music to try, and realised they weren't getting it here.
