It requires special attention when removing the ice cubes, ideally letting them melt a little. Unfortunately, I destroyed one compartment trying to hastily remove the ice cubes directly from the freezer.

The glasses do not hold up for long, within 5 minutes they had already opened on the side. It is ideal to use them with chilled drinks, they will definitely last longer. To enjoy using them, it would be good to have prepared several glasses in advance.
