I just tried mine for the first time yesterday. Went 11 hours without having to empty it, no leaks. Wore it all night, no leaks. And so far so good today (about 8 hours so far).
Definitely an improvement from tampons, you don't have to think about changing it, you can go number 1 and 2 without emptying it. You almost forget you have your period.
I found it easy to try it for the first time in the shower. I heard there was a learning curve but I had no problems right away.
I would definitely recommend it to anyone over tampons and pads.
