I love my Diva Cup.

There definitely is a little bit of a learning curve at first, but once I got the hang of it I wouldn't go back to tampons. I had previously tried the Instead cups but they never worked (too big).
I use the size #1 even though I am 37 as I am petite.
I travel a lot, use it in public restrooms, just empty it out, wipe with TP, and re-insert. In those cases I make sure to wash my hands before going in the stall. Then I just clean the cup thoroughly in the hotel room 1-2x a day.
When I was having super-heavy periods (on Paragard) I'd have to empty it once every hour for a couple of days, which was really annoying, but I'd be soaking through a super tampon in even less time.
