I ordered this as a gift for my older son who is a math and science kid. The quality of the piece is excellent. The printing is very sharp and the acrylic very clear. Having a sample of all of the elements, with the exception of the radioactive ones, arrayed before you in the chart is just wicked cool. When the chart is turned sideways you can see the width of all the samples. So neat. Maybe you have to really like chemistry to get how awesome this is but it is wicked cool.
I initially bought one of these as a gift for someone... but when I saw it in person I had to keep it for myself, as a desk ornament... I am a chemist. And bought another one for the gift. It is incredibly sharp and absolutely worth the money for anyone that appreciates chemistry.
