I got my Infiray C200. Super happy. Seems very good, both image quality and build quality. Fast menus and navigation (compared to a few other cheap meters I've tried). Supplied 16GB memory card has decent read/write.
One note though. Aliexpress sellers say the C200 is an upgraded version of C210, and should be identical.
This is not true. I contacted Infiray (Iraytek) and they told me only C210 and C200Pro has computer capability, and USB video.
The C200 will simply turn up as an external hard drive when connected. The supplied USB-C cable was also super flimsy, and kept disconnecting a lot (until I wiggled it to get a proper connection). Seems odd, since everything else was such high quality. Even the case has this rubbery/velvet coating on the outside and a super nice cut foam insert. Perhaps these Aliexpress sellers are replacing the cables with cheap ones, and selling the good ones
Nothing surprises me in China.
