I am almost done with my organic chemistry.I had a model kit before I had to buy this one.I was surprised that a model kit can be so important for students to understand and see molecules. I had a lot of problems with seeing and finding interactions and angles on my other molecular kit,I couldn't push or pull-it just was breaking apart and angles were not quite right, because it doesn't have the same bonding, and obviously it is very important in organic chemistry. This 1013A HGS Molecular Model has been made for students who is taking organic chemistry, the angles, the interactions between molecules, gauche and anti, the boat and chair... is easy to see, because the bonding is made just right. You can push and pull those bonds they don't fall apart.The other important thing about this set is- the size, it is perfect to care to school, you can even preassemble molecule-it will not be too big to care in your bag for your exam- very helpful! Absolutely love it- and strongly recommend for organic chemistry students.
I ordered this for $20, but then afterward found out that it was selling for $16 at my school. That really did not bother me much, as I like buying products from Amazon. However, what annoyed me the most was that it is impossible to make bigger molecules with this model. You can only make simple tetrahedral but nothing complicated as 1Methyl,3Ethylhexane or longer molecular chain. The Carbon atoms were not labeled properly. The bags containing the molecular bonds broke apart too easily. And frankly, it has horrible packaging. This is my first bad review product on Amazon and I hope it is my last. It was a huge disappointing.
So I just got this molecule set for my organic chemistry class, and I find it functional. There are definitely positives and negatives to this set. On the positive side it was affordable, and the small size of the set makes it easy to keep in my back pack. On the negative side the set is small and it is easy to misplace the pieces, also I wish there were more atoms; you can't make molecules that are bigger than 10 carbons and there is only one halogen. But aside from that it really is a decent set.
I purchase this set and it is very helpful for chemistry and organic chemistry. This is an excellent item for beginners since you cannot make large or complex molecule (specially long chain alcohol hydrocarbon, etc.). However, it does aim on the angles taken by the molecule and the repulsion of free electrons. They are hard to break, but one most be careful or the stick will snap inside the "carbon" and it would become useless to make a tetrahedral. It came before the estimated date. HOWEVER, the content came on a plastic bag instead of the plastic box of the photo. This make the set more uncomfortable on its management.
Cheap, but you get what you pay for. Comes with just enough balls and sticks to make one or two complex molecules. The container (zip lock bag) isn't too efficient for organizing the pieces either. You pretty much stuff everything into the zip lock bag, and hope nothing falls out while you assemble your model. If you can invest in a bigger box set, I'd recommend doing that if you plan to use this often
I'm taking organic chm and this model kit is perfect. Being able to hold and manipulate the molecules made the difference between a C and an A. It is large enough to make all the molecules I need, but small enough to be travel sized. It was delivered before the estimated time and was in perfect condition. I highly recommend it for any o chm student.
This is very useful for helping visualize various organic chemistry concepts and I would definitely say its use improved my understanding of my courses. The only bad thing is trying to take the models apart once you build them, but it comes with a rubbery tube piece to help pull the bonds off the atoms.
