The dividers are bearable for tablets and iPads etc. They won't loose or break easily if using them correctly. When inserting the dividers, please push them down all the way with some strength to ensure there isn't any gap, and don't leave too much spare room between the dividers and your devices so as to avoid loading too much weight on the dividers. When removing them, please don't take out by shaking them left and right, but just take out vertically.
