I was apprehensive to buy at first because there were so many negative reviews, but this kit is great! DEFINITELY WORTH THE VALUE. A lot of people spoke about missing holes on some atoms or being upset that the "instructions" are only in Chinese. But in my opinion, this is meant to be purchased for student purposes, i.e. we already know what is meant to be done with them. And the varied number of bonding sites is great for different molecules since an atom does not always have 4 bonds attached to it. Great for visualizing MOLECULAR GEOMETRY. And if you are purchasing for young ones, know that the colors do not actually matter! Or for whatever other reason you need instructions, just look things up on the internet, that's the beauty of living in 2023. Anyways, I'm very satisfied, it's been SUPER helpful for R/S configurations and stereoisomers!

Works great for my organic chemistry class and comes with a manual showing the different colors and the assigning elements.

My daughter was the first to received her chemistry set in her class.,There is no doubt that others going to purchase soon. Her friends are fascinated with it.

Firstly, I am a frugal chemistry teacher who is always on the look-out for a decent product for a good price. Secondly, I want something that students can easily manipulate without too much confusion. This kit is it. While the included instructions are all in Chinese, a quick Google Image Translation will help. My students were making molecules pretty quickly and they were able to discern the shapes from this kit. The only main difficulty, aside from the Chinese instructions, was that there were several carbon atoms with only 3 bonding sites. This might be good to represent Boron, but can be confusing to high school chemistry students. I had to sort those out and label them. If you're willing to do that extra work, these kits are great.

This writes so beautifully. How ever be cautious when handling the tips, they are very sharp.
