I love my mooncup! It's taken me a few cycles to get the hang of it - the first cycle I really wasn't sure about it as I could feel it pinching a bit, but I now know that I didn't have it in the right place. I've become bolder with it over time, and now I have no worries about shifting it around until it's right (tip: once it's inserted, give it a couple of twists to help it sit right). For me, the cup doesn't fully open up unless I wear it higher than the diagram suggests, but once it's positioned right, I don't even know it's there. There is a mindset change to make the switch from tampons (which I found convenient, but really didn't like the feel of, especially on lighter days - that awful dry feeling), as the blood is all a lot more visible, but I don't think that's a bad thing. It's healthier to be more in tune with what your body is up to. The environmental aspect of it is also absolutely huge for me - I hate all the plastic waste from traditional sanpro. I mix and match the mooncup with reusable pantyliners and period pants (which are also magical game changers that I can't believe it's taken me so long to find), and I feel totally liberated.
