Does not work with larger / wider bottles

With cans and 0.33-liter bottles the stacking aid works beautifully. With larger / wider bottles she unfortunately does not really work. Standing side by side, the bottles do not fit, because they are too broad. Leaving a holder, the bottom three bottles are indeed safe and but firmly, you put more on top, roll the lower but off to the side. :-(
I'm still not sure if I will keep the stacking aid or return again. Because actually it is in the bottle, which I want to stack to 90% for bottles from 500 ml, which are wider and usually larger.
