It’s going to be a LONG time before any orders are shipped. NFC Ring is currently in a patent dispute with Kerv Wearables and now Esos is claiming to own the patent as well.
Case is currently delayed until November 30, 2017 court date and will be ongoing from there. Guessing will likely be well into 2018 before it is settled.
