I tested both during this cycle. I'm so happy. No leaks, felt comfortable enough after the second day to go without even a panty liner which I haven't been able to do since I was 13. No pain on insertion or during wearing them discomfort on removal till I got used to them. I went to help a friend get caught up on paperwork at her job and was gone for 9 hours... I didn't even bring my purse. Being on my period and forgetting my purse would have been a disaster before the cups. I was able to sleep for a full 8 hours without waking up because I could feel my tampon over flowing after 4 hours or less.
I will NEVER go back to tampons.
