I bought a small and medium fan. They are both so similar in size and didn't know which to choose. The small one has 2 speeds, the middle one has 3. The lowest speed will most likely not be used because it's too low and equates to someone standing next to you and blowing in your face. A small fan is great for a small space where the fan will hit you directly - like a table. The larger one is only slightly more powerful, but can circulate air better in a small space. For comparison, I posted photos of a small and medium fan side by side. In addition, the color of the fan is nice, but not as bright as in the photos. It's a vintage mint green color, not as bright as the photo.
