Hello,

wanting to purchase a new JUC, I was wondering if the new closing system is as secure as the old one? For those of you who have both models (I only have one with the old closing mechanism) is there a difference between the 2?
Anything you could think of between the old and the new model would be helpful before I go to the boutique

Thank you
