I was particularly in terms of guidance quite pleasantly surprised, the procedure of building is quite reasonably explained (who has already often tinkered times that for such a simple circuit is not required, of course, find it still positive).
The basic mode of operation is explained.
Good also that the two ICs are socketed, just beginners but do more easily when these two sensitive parts do not need to be soldered.
Unlike another Amazon kit is rated at this also given that all values are equally 1-6.
