I've used my cup for one period and wish I had known about cups a long time ago. It's kind of hard to figure out a technique and I think it's probably different for everyone. The instructions say to turn it once but I couldn't turn it at all. I found that tugging and pushing on it a little did the trick. Sitting on the toilet didn't work either, for me it's the standing position. And even these techniques didn't always work as it would leak. Overall I love my new cup and would recommend them to anyone. There is nothing to throw away and you don't have to worry about always having a tampon with you. I would recommend that if your using a public restroom to always use the ones with a sink as it can get kind of messy.
