It has very good quality and does not come off the door of the cupboard at all! The ends it has to wrap the bag help a lot and there is no chance of it coming off.
I put it in the cupboard on the counter where I have a cutting board and directly push whatever I want to throw away and with dirty hands it falls into the open bag (without dirtying any trash can, nothing).

The only thing that requires attention is the ends which are dangerous, I understand that they are outward to hold the bag better and with more weight but you can easily get injured. For its price (9€) it should have found a way not to injure so much, I believe, but because it seems like a harsh criticism, I only remove 1 star for this.
