I keep on hearing it’s a flop, but where I live, Switzerland, they don’t sell it. So I can’t really say.

And I am not even talking about the badly taken product decisions for such a great headset but… how can they get devs onboarded for an app ecosystem for a device that can only be bought in a handful of countries?

Clearly Apple sold it and did their best so that it fails.

It's been 2.5 years and Apple still hasn't sold out of its test run of 500k units. About 350k of those sold in year 1, about 50k sold in year two, and less than 20K so far in year 3. Workers at Apple's flagship retail stores are saying they haven't sold one in recent memories. The tables displaying them are disappearing from stores. Roadmaps for all future goggles have been shelved. It's a flop and Apple knows it.
