DJI, huawei and insta360 are three off the top of my head that are perfectly capable of going up against global brands.
Additionally, almost every high quality brand has manufacturing in China; Apple, Microsoft, Nikon, Canon, Dyson, the list goes on.
This is more a problem of “you get what you pay for”. No name hoverboards were a real problem because designing a compact, high power draw, lithium powered device is hard to do. Segway, ninebot, etc all make great ‘hoverboard’ like products.
