The button that you suppose to press to sprinkle your food is also a button that opens up the whole Grinder. So if you press is a bit harder the whole thing opens up and you are ruined. Because salt inside the grinder just spills out everywhere...
The quality is not as good as I expected. The button that suppose to sprinkle the salt is also the butting to unlock the salt grinder, so if you press the button to salt your food a bit too hard the whole grinder opens up and basically you are ruined because it spills all the salt out
