Query: Not Very Durable

There are many interesting chemistry concepts you can expose to an enthusiastic youngster. I bought this kit for my son's eighth birthday. Found there weren't many experiments to try, explanations in the manual were simplistic, and key components were fragile and arrived broken. If it were more expensive and I felt my son would have cared, I would have asked for a replacement.
