Teardown and review of an ultrasonic cleaner from Vevor (China)

I purchased a cheap china made ultrasonic cleaner. Here is a teardown and review video where I also touch the electrical safety aspcect. The safety grounding was ok so as long as you use a receptacle with a ground connection and a protective fuse (with earth fault detection and isolation) it should be ok. I wouldn’t recommend spilling fluid inside the ventilation holes though so use care.
