Gynefix Copper IUD: its beads instead of a T shape!!!???

Ari
Does anyone have any information about this IUD called Gynefix? I'm located in the US and I know it's not available here,  but I've read some stories about how it is better than he Copper T shaped IUD/paragaurd and I want to know more.
I had the paragaurd and it was incredibly painful, it ended up shifting and I had to have it removed. 
I love the convenience of the IUD and I also want something non hormonal. So the Copper is best for me....
However, I'm terrified to have it replaced  (and go thru all that pain) just to have it removed if it shifts in my uterus AGAIN.
This seems less painful (from what I've heard) and less likely to move since it's attached to the top of the uterus and the beads hang down, therefore moving more freely with your body that the paragaurd. 
Any info at all would be greatly appreciated!  Thank you 💛✨✨
