Overall, i absolutely love the flex disc. As a young woman who has suffered from endometriosis for the past 10 years, i have never found a period product that was affordable, dependable, and made my period cramps bearable. Tampons always made my cramps more painful. It was a constant worry in the back of my mind to pack extra if i went out, to remember to change it every 4 hours, to be careful for tss, to make sure i haven't bled through my pants. With the flex disk, all of those worries, are gone. I feel so much more comfortable, confident, and much less held back using the flex disk. The only draw backs at all to this product are that it can be initially intimidating. It is very large, and therefore somewhat unfamiliar to use. However, it is so easy to get used to, and once you do, you won't want to go back to anything else. It is also somewhat difficult to discretely dispose of, and the plastic packaging makes it very noisy and difficult to discretely change. This comment is more for the design team haha maybe put the disks in some kind of quieter packaging that could double as a discrete disposing package for the disk you need to change and dispose of. Over all, i love the flex disk, i couldn't be happier.
