I have the small size to organize my spices in a small upper cabinet; they hold quite a few spice bottles, turn easily and fit within a small space. The design helps maximize the space and makes finding spices much easier. The clear plastic is nice and understated, the lip ensures the spice jars don't fall over. For the price, they are a must!
If you want to maximize area on your lazy susan, this is the one for you. The walls are thin enough that you almost get the full diameter. I tried another brand and with the wall, I lost a full inch of storage space.
