Query: Not durable, unable to 'bundle' length of cord

The winding mechanism has failed after a year or so of usage time at least 2x so far. The length of our cord is fairly long for our wooden blinds, around 5 feet, so the winder can't 'wind' the entire length of the cord. It does the job reasonably enough that I'm not replacing the ones we have in place right now. However, when they break I'm not getting blindwinders again to replace them.
