I was only remarking that often things are said which wouldn't happen face to face
OK I will see what I can do.
One of the thoughts which comes to mind is if these devices cost as much as something you could order from China off of ebay, why not just buy some of the ebay drivers and characterize them to see what they can do? Maybe some of them are actually up to their stated ratings and have soft start built in and all at a price we can't duplicate on our own?
One of the reasons I don't like to buy drivers from China is that so many of the sellers outright lie or don't know anything about what they are selling. If I knew the real information about some of those drivers, I'd buy them, if they passed muster. Although building your own, making your own design is more fun as well as furthers your understanding about the devices
