We bought roller blinds in the spring and made them to order. So the quality of the curtains themselves is good, we took 3 blackout (dense, do not let light through) and 1 day-night (it's amazing, no questions asked).

It is clear that they have saved money on the mechanism, and there are conflicting feelings
