I actually like the invite system. People complain when they order their phone, then have to wait up to eight weeks to actually get it (iPhone 6 anyone?). This way you don't have to give them your money until they are ready to get you one.
Point is, people will complain no matter what. At least this way you keep your money a bit longer, and can just not order it if you find out it's a dog.
