I just watched the interview, motivated by the other thread (the eBay ordeal).
I have to say I found Mr. Qin a very nice person, very well prepared for the interview and with an honest face. His presence and effort in trying to communicate dignified his brand. I would easily have watched another 15-20 minutes of this interview. One question I wish Dave had asked is what is Siglent's plans to expand to other regions, specially South America.
Kudos to Dave for bringing Mr. Qin and I hope this type of video becomes a trend. It's things like this video that are making EEVBlog stablish itself as the most influential EE (in all levels from hobbist to pros) vlog and forum on the internet today.
Yolo, ya!
