Diva Cup Help?

Hello, I've been looking into the diva cup for about a week now and plan on buying it soon. I've heard nothing but good things about it, which is cool, but I wasn't entirely sure if it's for me. I've tried, and failed, inserting tampons, and I'm tired of having to pray my pad doesn't fold or cause a leak. I'm skeptical but still hoping that the diva cup will be a good investment. Any advice, praise, or warnings?
