From the product page where it was purchased:

[5-Level Adjustment] The ultrasonic cleaner is equipped with a 5-level timer function (90 seconds, 180 seconds, 280 seconds, 380 seconds, 480 seconds), allowing you to set the cleaning time according to the degree of dirt and the usage scenario.

[600ML Large Capacity] The ultrasonic cleaner features an improved design for its exterior and dimensions, making it compact and exquisite. With a 600ML large-capacity stainless steel tank, this ultrasonic cleaner is very convenient for cleaning items such as eyeglasses, dentures, braces, watch metal bands, toothbrushes, and combs. Additionally, the included cleaning basket is useful for washing small items like earrings, necklaces, and rings.

[DEGAS Function] This ultrasonic cleaner is equipped with an advanced DEGAS function that removes dissolved gases from the water, reducing the oxidation speed of the items being cleaned.

[360° All-Around Cleaning] The household ultrasonic cleaner generates bubbles in the liquid-filled cleaning tank with 48,000 high-speed vibrations per second. The shockwaves created when these bubbles burst lift dirt from the surface. It thoroughly cleans dirt from all angles (360°) without damaging the items.
