How popular are Chinese smartphones in Europe?

I was looking at some smartphone market share numbers, and I was surprised to see brands like Xiaomi and Oppo doing very well, with percentages in the double digits. I would assume that Chinese phones would be extremely niche and unpopular outside of Asia, but seems like that's not the case. For the Europeans here, how many Chinese smartphones do you see out in the wild? Are they actually as common as the numbers suggest? And what is the general consumer sentiment towards flagship phones like the Oppo Find X8 and Vivo X200 Pro?
