Very good. Be careful, you need to have a saw to bring it to the size you want.
Just like you need to buy the corner column so that it doesn't hang down and break.
Durability will show.

I set up the curtain in a Γ shape and if I remember correctly, it is 1.50 x 70. I can't say that I need it, so I didn't put it up.

Simply necessary. It should be sold together with the rod and not separately. The only reason I give it 4 stars instead of 5 is because you have to cut it first to the correct length before screwing it to the ceiling. Unfortunately, the Allen key that unscrews one end in order to cut it does not come with the rod, nor is it accompanied by instructions for this step.
