I used a disposable one called Instead Softcup. It worked pretty well, but there was a learning curve to get used to putting it in and taking it out. And I wouldn't recommend it for women who have a really heavy flow because accidents are possible and super ultra embarrassing. But if you have a normal flow, it can be a good alternative to tampons or pads once you get used to it.
I love my moon cup! So much easier and cheaper! Use a liner till you get used to it.
