Yeah my former boss bought 2 of those to test it out a couple of years ago.  

Personally I find them rather slow, likely due to the use of EMC (flash) memory/storage that is slow.  Windows 10 startup is really slow to the extent it is also unuseable.  Booting to Android is bearable but not that great.

Granted that was 2-3 years ago so things could have changed, but certainly at the time it seemed like a great product bu was probably let down by the use of EMC memory/storage…

I bought a Chuwi Hi 9 Air tablet off Aliexpress in 2018, which is still going strong today. It had pretty good specs at the time for $170 USD (2560x1600 display, 4GB RAM) and the hardware has held up fine.

The downside (and I suspect this might be the case with a lot of their products) is that Android updates came to a halt not long after it was released. Fortunately, it came with an unlocked bootloader, and it was fairly easy to get alternative Android versions installed. I don't know that I'd put a huge amount of money into one of their products, but I've been pretty happy with my purchase.
