I just posted about being frustrated and confused about all the different cups out there. I discovered this website which has a really cool feature - if you scroll down, you will find "cup comparison tools," and two scrollable pictures side by side, so you can compare two cup sizes. For example, I have a Diva cup and am not very happy with it, so I kept one picture on "Diva Cup 1" and used the other picture to scroll through and see other cups as they would compare to the Diva cup 1. Very cool. This has put my mind so much more at ease. If you would like more of a visual comparison to go along with the charts out there that just show numbers, this might really help you.
