YaeCCC 110V Ultrasonic Cleaner Power Driver Board with 2PCS 50W 40K Transducers

I built a setup out of a soup pot, mounted the driver board in an old computer power supply box, wired everything up as per the instructions in the FAQ (plus I added a power indicator), filled the pot with water and made a bzzt noise for five seconds. Power light was still on so I touched the pot to see if I could feel any vibration and got the electric shock of my life. Go figure I waited past the return window to try it, but how exactly am I supposed to return something that gets epoxied on anyway? Screw this garbage; it's going straight in the trash.

I took my time making everything perfect. I epoxied both transducers to a heavy gauge 6" deep hotel pan. Soldered all electrical connections.I turned it on for the first time, and was surprised to see that 100w of power hardly made a ripple on the surface of the water. After testing with a few miscellaneous items, with no real improvement, I tried the foil test. Fail. I also tested a friends old Harbor Freight cleaner, to make sure I wasn't expecting to much. His punched holes in the foil easily.I might try adding another set to see if I can salvage the project.

The instructions for wiring the board and the transducers is impossible to understand! The listing says contact seller with questions. It is not possible to find contact information.Not happy!

It stops working after 5 minutes of use and then I have to wait 24 hrs to use it again. Unfortunately it is too late to return it. Don’t buy this garbage.
