I use a section of another brand, and ordered the Diva order to have a second in troubleshooting. But I was disappointed. The Diva is good, but I find it too soft, and it's a big flaw. Indeed, it is difficult to position correctly, and above all to be deployed to ensure proper sealing. So I have known leaks that led me to give it up. I still have it at home, and I may be happy to have on hand when needed, but I did not like its use. My other cup is slightly stiffer (while being flexible enough for use without problems and perfect comfort) and deploys the first time without any problem and without having to contort me ...
It is a purely personal opinion, maybe other users just appreciate this flexibility.
However, a good point for the pin comes with and which I use to clean the small air intake holes. I do not know if it is made for that or just to be flown on the back of a jacket, but it is very useful!
