Couldn’t be happier with my flex disk! I work in the woods for 10-14 hours a day and love the hands free emptying of the disk. Bonus that I don’t have to carry the dirty tampon/pads for the rest of the work day. I tried menstrual cups in the past and had no luck plus now I have a copper iud and wouldn’t be able to use the cup anyways. The disk works so much better!!!!
Only problem I found is on the really heavy flow days you have to be aware of emptying your disk frequently. I haven’t had any leaks, but I have had it overflowing and… it is a mess to say the least. But being aware of your body and emptying the disk more often than you think takes care of the problem! The disk works almost too well and I can forget that I’m on my period.
