I bought a new innokin Cool Fire IV and an MVP 3.0 pro and they came today. The codes on the box come back and say they are real products. On Innokins website it says that the cool fire IV and MVP 3.0 Pro have authentication codes directly on the device. The cool fire had the code come up but innokins system isn't finding it, and the MVP's code is coming up as just a bunch of 0's...should I be worried or are the codes on the box proof enough?
