Saalt cup sizes

Has anyone tried both sizes of the saalt cup? (small and reg)

I purchased the small cup to try during my last cycle and overall I love it, BUT using it this cycle I realized it just doesn’t stand a chance on my heaviest day. Most days it last me around 10 hrs with little to no leaks, but on day two I have to change it every four hours or so, which is still better than tampons, but not as nice as I was hoping.

I’m considering trying out the regular size, but I don’t wanna spend the money on it if it won’t make much of a difference, it doesn’t seem to be that much bigger based on the pictures I’ve seen online..
