They definitely going to have to work out some issues and change policy. Seem to be a major breakdown in communication between one to the other. That I saw early on in the thread, as I don't believe the GM knew the full situation till later on, not even sure if the CEO knew about the issue? That was clear by the way he responded and was first to apologize not knowing the full details. The marketing manager, or the lady they claim that sent out the notice on the other hand, knew exactly what she was doing, evident in the follow up PM to readjust price and was used to protect local distributors, which is illegal and just a bad move.
Now that being said do I think they make bad products? The answer is no, otherwise won't have upgraded to the SDG2122X in the first place and reason I listed the older model on eBay. I think the price for performance is great and if Siglent made some major changes and focus on the right areas, improving communication with the engineers and software developers so they can work out firmware bugs much quicker will be a huge step forward in the right direction. As hardware is not the issue and good quality. If they get that accomplished, I think they can surpass what the competition has available for the price and be a major player. Even with the current dispute in process I still somehow have some hope for them, just maybe not with the current structure they have in place. As using a marketing manager to watch eBay listings to she can enforce policy is a huge waste of time and resources, not to mention it will get you into serious legal trouble. One area they sure consider is being more proactive on the forums instead and listening to customers for what they want, complaints and bug reports and assigning a staff someone that a engineer, or software developer to read forum treads and take in complaints directly. So can be more efficient and get firmware updates faster and better support overall. That how you win the trust of your customers back an take it to the next level. Dropped the whole grey area enforcement of eBay listing altogether, it won't end well, no matter how you go about it and it's non productive and will damage what took years to built up. Yes everyone make mistakes, it how we learn, the mistake she did was not really a mistake, she had her reasons, or was instructed to.
I am only saying this as I work with large to midsize companies and seen first hand them succeed and fail and usually when they fail, it could have been avoided, in most cases and is usually due to lack of wanting to change and sticking to old habits and enforcing shady practices. I hate to see Siglent go down this road, as after the improvements I seen them do with the hardware, it be truly a shame to throw it all away on stupid shady practices, if anything is having a opposite effect on them. You don't want to kill the USED market value, as then people will see no resale value, or hard to sell and buy from the competitor.
