Lunette cup

Not sure if an okay group to post in but does anyone have experience specifically with Lunette menstrual cups? Or any at all since this is my first time buying one. I just ordered one online and want to know what to expect, if there's anything I should know since I've heard some brands have issues in certain areas like leakage and fitting that they don't really tell you how to deal with in the packaging 😅 Any tips and tricks?
