Yes, DJI literally shocked me when I bought the Mavic. They completely bust the stereotype that China is bad at design and innovation, e.g. "Designed in California, Assembled in China". Everything from the build quality, to the packaging, documentation, software, even customer support has impressed me.
They're like the canary in the coal mine, a wakeup signal for the Silicon Valley that thinks they're still on top because design and innovation happens here, and China is only for lower-on-the-supply chain stuff. If companies like DJI replicate, and China gets a few dozen Samsungs and Sonys, which become global brands and symbols of high quality instead of regional brands, one of the shining sectors of the US will have been caught with its pants down by misjudging their competition yet again.
