In other reviews there were a couple of complaints about the kit not being realistic. However, the bond stiffness and design are surprisingly realistic (molecules aren't all that flimsy). The kit is perfect for create virtually any small organic molecule. It is excellent for seeing the difference between a chair and boat conformation, provided that it is put together appropriately. (My organic book and the directions were useful in arriving at the right conformation when I had problems.) The kit may just take a little bit of time to get used to, but it definitely is worth the work and time to see molecules in 3-D!
