This product addresses the basic problem of the Chemistry set I had and loved as a kid. After a week of working out what got hot and melted stuff, I had run out of chemicals!!
By getting new supplies monthly, it paces the learning and paces the fun and you always have a new experiment to try next month!
Not sure how it will compete with all the DIY stuff you can learn with stuff around the house that you see on You Tube, but for a more serious and structured approach to learning Chemistry, this has to be a great product :-)
