In the hands of my grandson this gift is golden! He is fascinated and challenged by this science set. He works/plays for hours at a time, building different elements. I am amazed by his deep interest in this activity. It certainly captures his attention! It was not an expensive gift either!

Item arrived on time and in great condition. I used it to study Data Structures.

I got these for a simple lesson I had to teach for 6th graders. They were exactly what I needed to build simple molecules for my lesson. It comes with many little pieces so I was able to build enough molecules for the kids to pass back and forth and discuss.The molecules fit together well, nothing fell apart as the kids examined them and they made the lesson hands-on and interesting.

It was very small, I imagined as a “444 piece set” it would come with many pieces, however I could not even make every simple molecular shape with the pieces given. It also only came with 2 lone pair pieces, so its more so of a product to use and break apart, rather than use to reference to study. The pieces that included the buckyball were surprisingly secure however, definitely fun to make the ball. However it comes with no instructions on how to make the ball, so you definitely need to know how to assemble it, but its quite easy. (Hand to reference the size of the set, along with the chart of molecular shapes, as the set is just barely able to make them, with not much more pieces to be able to make other molecules.) However, its lack of pieces makes sense for the price.

Great for visuals to see how chemicals are combined rather than just learning the chemical, itself. Also, these are color coded with the periodic table, which helps with that too! Great tool for beginning and established scientists.

I ordered this set for my chemistry class in my homeschool coop and it was missing 3 purple pieces with 5 holes to make a trigonal bipyramidal model. I contacted the seller and asked if they can send me the missing pieces as I need them for my class. Instead of sending me three 5-hole spheres, they sent me another complete set! I’m truly impressed and grateful for their amazing service. As for the modeling kit itself, it seems really well made. The holes are just the right size, not too tight and not too loose. And I choose this kit because it had more of the 5-hole and 6-hole central atoms which are what I needed for my class.

The media could not be loaded. I liked the fact that a key was provided. My only problem was the packaging. A see through plastic container with tighter locks would have been better for me.Overall this is a useful product. I can really see how instrumental it will be in my classroom.

Good product for those trying to gain some foundational knowledge on the behaviors of different atoms and organic molecules
