Duluth Labs Organic Chemistry Molecular Model Student Kit - (88 Atoms and 140 Bond Parts) - MM-004

I purchased this set for my college Organic Chemistry class, and I must say, I am impressed. After researching for a few days and comparing this set with other models both sold on Amazon and from other sites, I concluded that this set would give me the most bang for my buck. Plus, it is eligible for Prime shipping! So how can you go wrong, really? It has a lot of pieces, enough for me to build and compare multiple molecules at once (I purchased the large set). I found that the atoms and bonds held together well, but still allowed me to manipulate their connections and easily visualize different chair conformations (which was the primary reason I purchased this set). As mentioned in other reviews, the box is a little flimsy, and probably wouldn't stay shut just bouncing around in a backpack. I plan to fix this by putting the entire box in a large ziploc bag, or using large rubber bands to hold it shut. The edges of the box cover also feel very sharp, but overall the pros of this purchase greatly outweigh the cons. Customer service is great, and I was contacted after my initial purchase of the set, and again upon its delivery! Very pleased with the quality of this set, and the seller! I would especially recommend this set to other college students.

Amazing model kit. The pieces are easy to fit with each other and it is also very easy to take apart. This means less stress on the hands and allows you to construct your molecules faster. The customer service is outstanding. As soon as my product was shipped, I was contacted by the seller to thank me for my purchase and to assure me that I was happy with it. As soon as it was delivered, I received another message from the seller asking me about how my model kit and I were doing. I appreciate the amount of dedication provided by this seller. Highly recommend this model kit on the basis of its quality, ease of use, and the exemplary customer service that comes with it!

I was looking for an affordable molecular modeling kit that had plenty of parts for building a larger number of molecules. I settled on this one and am glad I did. It has three sizes of connectors, the longest of which can be used for double bonds. The parts fit easily together, but tightly so they don't fall apart. This is almost identical to the one we have used in my college lab, so it works very well for my needs. The only thing that I did not like was that no guide book was included in the package. However, the company did send one as an attachment to an Amazon message. It is many pages long and would not have fit in the box. I'm glad I checked my messages or I might have missed it. I would buy again.

This kit is great for O CHEM students! I'm in university and i use it when ever i need to visualize a molecule.The only thing i wish they had included was separators for each molecule, by itself the box rattles a bit. Also it would help with sorting.That's why i gave 4/5, more like a 4.5/5

I love this model kit! I've gotten smaller ones before but this one is great because it has more pieces which allows for more intricate models. The bond pieces are durable and form stable connections but are still easy to remove. The company is even better than the product! The kit arrived on time and the owner personally emailed me instructions for my kit and checked to make sure that I was satisfied. I was so impressed that I decided to leave seller feedback (which I rarely do) and then the owner emailed me to personally thank me for my feedback!Bottom line: this is a great product and an even better company!
