You never had to pay to be invited. Existing OnePlus One owners can send out as many invites to people as they want for free. This is just a way to get them without knowing someone else who has a OnePlus One.

why is everyone acting as if its some luxury class phone. its just a cheap Chinese phone that has a poor company backing it. too poor for ads and too poor for manufacturing mass amounts of their product. I wouldn't trust them with making my phone
yeah build quality. if its as good as everyone makes it sound, why didn't they put more effort into advertising it and mass producing it. it would sell like hotcakes, especially for that price. something is fishy here
