Probably the most pathetic product I have ever seen.
Has anyone tested it? Does it actually reach ultrasonic frequency? I would be very impressed actually if it did.

I'll try cleaning two equally dirty coins in soapy water with it as a test (one in that piece of engineering shit and one just soaked in a cup)
i wont be able to test if it emits any useful ultrasonic sound wave tho, but i hardly doubt it.
even if they can generate some, degrading the power from the batteries will affect it.

>Brand new & High quality
>Sonic vibrations up to 5800 waves per minute

>5800 waves per minute
5800/60=96.7
96.7Hz ain't ultrasonic

Oh shit I missed the minute part.
I was about to say 5khz was shit but that is pathetic

>>928468
it's literally a vibrator motor and a switch. I might as well re-implant it in a cucumber and stick it up my ass, desu...

So literally stirring the solution will be more effective than this ultrasonic buzzer.

doesn't matter, тbh
a toothless chav on youtube review this piece of shit, about his "vaping tools" cleaning and described it as "well working".
Who would have though some soap and water would get rid of his saliva and human slime...

You shouldn't even bother with anything except professional units from watch repair or jewelry supply stores and those start at around $200 for a tiny mug sized cleaner.

it was more of a curiosity what scheme would the crafty chinks think of this time, тbh...
