I've never used menstrual cups before this one so I wanted to start with one that made it easy. It is very easy to insert, but it does take some practice. Anyone leaving reviews that it's uncomfortable or impossible to put in are most likely doing it wrong, not relaxing their muscles, or not pushing the cup up high enough. I leave the cup in all day (I empty it once in the morning and once at night) and completely forget I'm on my period most days. I will say that I've had some issues when removing it though. For a while, I could remove the cup by pulling the tab and slowly removing the whole cup just by pulling the tab. After using the cup for a few months, when I continue pulling the tab slowly, the stopper inside pops through the hole at the bottom and blood spills out. It's a big mess and makes removing the cup a lot more difficult. If they could make the stopper inside just a bit bigger, I don't think this problem would still occur. Other than that, I love the product and I will continue to use it regardless. I also recommend the foam cup wash.
