HaJoW I guess not. The second picture (857c2249-a983-4374-a883-e78ef3f2013e.jpg.webp) shows no ultrasonic parts. Real ultrasonic cleaning can not be powered by two AAA-Cells. Also, the price is far too low.

matrix It'sa sales practice that is illegal in my country. If they were selling here they would be bound by law to honor the most visible price. That would be the price on the email they send you usually but being international they get away with this misrepresentation it a lot. There are a lot of scams on these sites. This is just one of the easiest and most blatant.

Q: for esc 50a which one is the recommendation?

matrix None of them can be recommended. This is terrible solder. It is contaminated with something that pushes the melting temp too high to allow the solder to flow and bond properly.

matrix Now that I am trying to use the solder I can say that in 40 years of electronics this is the worst I have used. Its melting point is higher than my irons can handle cleanly and it acts as though it doesn't contain rosin. I haaven't managed to do anything but cold solders and burned boards with it. I don't know what is in it but it doesn't work like any tin lead solder I have used before. How do I take away the five stars I gave it prematurely.

matrix Correction: It's input is 100 Volts I believe. The Signal generator is 3 volts on the DC rail square wave and 2 volts on the other waveforms.

matrix No. I wish it could for lissajous figure study but no. It is open source though so a crafty coder could probably make a firmware for it to do this.
