Indispensable for cleaning earring clasps Alpa, unless it done in jewelry. So independently, I can clean up my jewelry (it revives shine I did not expect), it sometimes takes me to look for other objects to be cleaned so it's effective. It is clear that the cleaning can be done with water but personally I have appreciated the efficiency with the product for ultrasound cleaning. The device has 3 different tempo; 3, 5 and 10 seconds but several cycles are sometimes required, especially for silver coins stained. Its operation is not very noisy but it becomes quite quickly however unpleasant, I therefore used in a different room than where I am.
