After getting some air outside figure clear things up a bit. I am not a competitor to Siglent and didn't just randomly decide to pick on them, overblown the situation. I spend while on the phone with eBay legal team, not customer service on the matter to find out exactly what happen before assuming. At first before calling eBay customer service then legal team directly. I took it as 3rd party just messing around trying to get rid of my listing, so the 3rd party seller could sell for a higher price, or eBay software screw up that false flagged it. When I got off the phone with eBay legal team was pretty shock what I just heard that DMCA takedown order for alleged trademark infringement for a counterfeit item and directly from "Siglent technologies co. ltd". I pretty much knew exactly what the deal was and reasoning at that point, as doesn't take much time to do the math, all you have to do is look up eBay search results for sold used items and you will see lack of used Siglent items that show up as sold and the fact when listing the generator I based the price off one that sold 2-3 weeks ago that now magically disappear. I seen one other company name I won't mention here do this before for same reason. It's more common then you think. Then have you ever seen a fake Siglent item? Over the years I haven't known, or seen even one listed at all anywhere and costs would be to prohibitive to the counterfeiter on a low volume item and the fact people only buy test gear when they need it, not a cell phone mass market item. Then the fact I used my own pictures and wording and was clearly listed as used and MINT in big letter, so no reason to even suspect it a fake, or never pretended to be a authorized dealer. So zero reason to have my listing pulled and now have unnessacry violations and restrictions on my account due to this mess. As eBay don't screw around with claims of a counterfeit item, due to lawsuit's and backlash they received of them allowing it for so many years in the past.
Before the false illegal DMCA takedown order for alleged trademark infringement for a non counterfeit item. I actually bought a new Siglent sdg2122x function generator, as seem to be good price for performance and have a Siglent SDM3055A meter that with the firmware update works well and is now quick. I saw Siglent as getting better over the years and seeing quality of components on the new Siglent sdg2122x function generator in Dave's teardown, despite the oversampling, figure would be a great addition to the bench and improvement over the old model I had. Even despite the dispute currently, took it out of the box and can say built extremely well and quality gone up. Haven't tested it fully. So if it wasn't for the false DMCA takedown order, I more likely would have been a big supported of Siglent, as I saw them improving over the years, at least what I use to believe. This shady tactics they use showed their true colors unfortunately.
That all being said I do know more then one person was involve and a women did sent the notice. The reason why I know it more then person and more likely common practice is the PM's from a different person then the one that sent the notice. Plus the search eBay results paints the picture. Do I think the GM was involve, more likely no? He seem to not know the details which tell me he wasn't informed till after the fact. It could be very well that one part of Siglent, or HQ as I know they have more then one. Then that raise more questions then it answers and is a much larger problem within the organization itself. Do mistakes happen? Yes all the time, I made some, as well as anyone else will, but this was done deliberately for price fixing and to monopolize the marketplace for your distributor's and quite illegal and also perjury due to notice was sent falsely causing irreversible damage to that account and not a small account and pull large numbers, I did over 2100 transaction. Lucky didn't get suspending and banned as a result, as that usually what happen when you sent a DMCA takedown order, especially for alleged trademark infringement for a counterfeit item, as it breaks eBay TOC, then they take legal notices very serious at that point and yes they do give you a violation and lower account standard level and they put restrictions, so it not a simple takedown. So definitely a apology not going to be enough to correct what you guys consider a mistake.
