I have a very heavy flow, and I can say after using this reusable disc that I had my first ever pad/tampon-free period. I wore this disc and a pair of period underwear (didn't even really need the period underwear, the disc didn't leak), and I had the cleanest and loveliest period of my life. I will say that something about the rim makes it hard to stay pinched when inserting, but I got the hang of it after a few insertions. Something helpful for me was inserting the disc while I was in a deep squat in the shower. Made it easy to slide in and push it past the pubic bone. Removal is a little messy, but in the shower it was no problem. It feels cleaner, healthier, environmentally conscious, and gave me such peace of mind about leaks. LOVE LOVE LOVE this product and I'm so glad it will last such a long time.
