I did not read quality instead of quantity
This is your problem, not mine.
Why is it assumed if your a hobbyist your "not doing production of anything"
If you have hit the stage where you have commercialized a project, gone through the motions for ramping up sales interests and have generated orders
in quantity, then you're no longer a hobbyist. You have moved out of the Hobbyist realm and into the professional one.
I'm not focusing on the rest of the sentence around quantity.
Then the rest of what you wrote is of no consequence. If you have to modify the sentence to fit your desired narrative, you're not only being intellectually dishonest, but you are admitting you don't actually have an argument against what was written.
I'm designing a focus controller for my telescope. it has to survive the heat and cold. it has to survive outside. it has to be durable. it has to be stable or it will ruin my images. it has to work and work every time I use it.
Bespoke things are not necessarily junk things. But there is a star system's worth of gap between bespoke one-offs, and turning a thousand units in a sitting. Until you reach the point where you have done this, your opinion and feelings are irrelevant. This is not a thread in which everyone gets together and champions the greatness of their one-off items. It is a discussion that is very specifically about the use of Rigol Instrumentation in a production environment. Unless you are asking questions to learn yourself, or you have production experience to contribute, your self-aggrandizing is entirely without merit.
