The whole time I was worried about leaks but I didn't see any so I didn't take it out at work. It was filled up to the first ridge so it was a bit full but not to the top so there was no spillage coming out. The down sides are that the stem rubbed me the wrong way all night long and I did notice I had to urinate more often which is kinda hard when you are working in production because they don't want you to leave.
So my conclusion is that I like the Mooncup but the stem has to go. I did grab the base without grabbing the stem so I am kinda confident I don't need it but I'll probably leave a little left since I have a long canal.
