Ultrasonic Cleaner with High-Frequency Vibration - USB Rechargeable, Multi-Purpose Jewelry & Watch Cleaning Machine for Glasses, Braces, Dentures

This device has no relation to ultrasound (> 20000 Hz). The picture attached to the description confirms that the vibration frequency is only 120 Hz. Therefore, there can be no talk of any cavitation effect. Ordinary mechanical shaking. The result is corresponding.

Arrived in good packaging, the instructions are in Chinese, which is inconvenient, we will figure it out.
