I just got mine in the mail yesterday which happened to be the first day of my period. I found inserting it really easy and haven't had a leak at all (yet, fingers crossed). When I tried to take it out the first time I didn't break the seal properly and it felt like I was trying to suck my cervix out with it. (Sorry for the over-share) OW! That caused me to panic for a few seconds but I tried again and it was easier. I'm still not totally comfortable taking it out. But there is a learning curve. All in all I think it will take a bit to get used to it, but I will probably end up liking it.

I ordered it from lunapads and got the diva cup and lunapads pantyliners kit. Wow! The pantyliners are so so so comfortable. I never would have thought I would want/like re-usable pantyliners but they're my favorite thing right now. I wish underwear felt like this. So much more comfortable than disposable liners.
(And better for the environment, too, of course.)
