I don't have anything to compare it to, however, I've had some leakage from what I now realise was incorrect insertion. I found it's not big enough for my heavy flow on first couple of days of period. It is a bit awkward and messy having to change in a public toilet but it's good to be able to go longer without needing a bathroom break. I've only used it for 2 periods so far so I'm confident things will improve. I may try a bigger cup for my heavier days.
