I have always been a bit naive, so may be doing it again. Tautech has helped a lot of people with countless scope/awg questions and problems. most Siglent based, but not all. He has done in depth research to offer solutions to various problems, which sometimes takes days and several posts.
It helps that I have a range of demo models that I can replicate issues with and/or offer advice usage.
He is openly the New Zealand distributor for Siglent, so helping a guy from Romania or the states is unlikely to foster a sale for him. Maybe Siglent pays him by the post, I don't know,
I don't get one red cent from Siglent for my efforts here other than the feedback from you guys to pass to Siglent whether it be good or bad which then enhances product quality and functionality and then we all benefit.
They send me a small Christmas prezzie (and last year one for Defpom too) as some token of thanks for our efforts.
Other gratitude's received was a nice lunch when I visited the factory some 5 years ago and more recently a free pre-production DSO to beta test.
The massive pool of experience here has helped Siglent improve all their products which of course translates into better marketplace acceptance and increased worldwide sales that I might also share in.
Going forward, I too am learning each time new products are released and try to hold at least a demo model of new products so to have some familiarity with them for local and EEVblog support.
Unless there are language issues I try to do all this here on EEVblog so others that strike the same issues can learn from it too. Support to EEVblog members via PM is NOT my style.
I should add that the complexity of modern equipment can be a hurdle even for those with some experience and what may seem like a bug is often a usage error. However please keep posting about things that aren't understood as there's always someone ready to help within a short time.
To those that may have not had the help they expected or hoped for, well I am human and can make mistakes.
