Menstrual cup from wish?

I have been interested in the menstrual cups for a while now and I saw one while scrolling through wish that was free just pay shipping. So I got it. Probably dumb idk. Does it matter if you get a random brand. I don't even know what brand it is. Haven't used it yet it just came in the mail. How do I use it? Make sure it's inserted properly how far does it go in? Does it even look right? I expected it a little shorter I guess. Help me lol. And is the last picture how it should look when you 'push down fold'?
