Its Very Hard for Older people to climb up in a chair or on a step stool to a fix the blind when you rolled it up ,or want to unroll it .
But as long as the companies make sure all the kids dont wrap the cord around there neck and choke because the parents didnt fix the cord where they couldnt get it Forget the Older people who might loose there balance and fall while trying to unroll it and dont have anyone to do it for them Thats OK though !!
