RELIANCER Molecular Model Kit,419PCS Organic Molecular Chemistry Set w/Atoms & Bonds,Molecular Structures Building Kit for Chemistry Learning,STEM Science Kits for Teachers,Students,Young Scientists

Bought this for a college student taking an organic chemistry course and the student loved it! Excellent support for “hands-on” learning!

My students use these to build models of molecules and compounds. It provides them with a visual of a concept that otherwise would be rather abstract to them. This is a quality product, and it comes with everything the students need to build their models.

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.

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.

I bought this set over the Old Nobby set because it had so many more pieces, and there were several in this set that were important to me that other sets do not include. 2,3, and 4 hole carbons have been helping me visualize bonds at different angles. Also the set includes 3 “electron cloud slices” that I use to visualize lone pairs. A lot of sets do not include these. This set also includes purple connectors for visualizing double bonds. I love that. (less pieces to assemble). The only downside to the set is the box it comes in. No dividers, but the parts are separated in small bags. I got this box at Michael’s for 5 bucks (on sale), now it’s perfect.

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!

The parts are high quality plastic and the size I expected. Good for demonstrating chemical compounds and bonding. Instructions were really little more than a parts list. I would have appreciated a few pages with further examples and description of how different length bonds might be used. I bought this set to begin talking to my 5yo granddaughter about atoms and molecules. Simple organic chemical reactions can be illustrated, showing how bonds are rearranged, and even talking about why. For example, CH4 + 2 O2 -> CO2 + 2 H2O.

My 11 year old son loved this for his Easter gift

Kit arrived quickly and safely. I am impressed with both product and service. Thank you.

Me agrado el kit sobre todo que trae muchos pares de electrones libres y me ha sido de utilidad para las clases de estereoquímica. Buena relación calidad-precio.

Fácil de armar y una excelente opción para demostraciones y método de estudio

Pude trabajar algunos modelos de moléculas y fórmulas químicas con mis alumnos, estaban emocionados cuando armaba el modelo 3d

Muy buena calidad
