We must be the only ones who have had no problems with the blinds. Maybe the ones in our villa where attached correctly, but we can't understand what all the fuss is about. Someone above mentioned it took about 20 pulls to get them up. At about a second a pull that is 20 seconds, 30 tops.
I do feel for the people who received scrapes or got hurt trying to reach the beads, but we didn't have that issue.
