Have lurked for a while but have decided to register to comment on this situation.
While its not perfect that the Carbon Fiber ring is not ready, this is the reason why we have Kickstarter. If John and the team had to do this the 'old' way then we may never have seen the product at all. Using Kickstarter to fund this 'start up', they have been able to correct errors that may have sunk them before they were able to sell the amount they have done.
A lot of the technology we take for granted has had a lot of missteps and the NFC ring has unfortunately suffered a few. The Team will continue to honor our order of Carbon Fiber Rings when the product is of a high standard that the community requires. Of course if thats a problem then hey I'm sure there is a rip off ring available from Ebay now.
