@P.A.M. what you are discussing is impossible and impractical. This manufacturing process has integrated multiple revisions and changes over the past 10+ months. I've witnessed the last contract manufacturer who was building the Milaana first hand once their production facility had the Milaana under assembly. If this type of manufacturing was being done in China, it would be incorporated from one batch to the next, since we are working in much smaller volume, we can implement it on the fly.
The issue with identifying this is with units that have been completed for the past few weeks while the guitar pick modification was being implemented. New copper has been ordered and waterjet cut that has caused a number of already manufactured Milaana to sit waiting for a battery cover. I'm sure Ryan will keep units separated the best he can as we transition to our shop handling the manufacturing of the Milaana. The issue is that there will be some units with the newer guitar pick modification and matched copper that will not have the turbulator.
The Turbulator is an improvement, but it in no way is monetarily feasible to offer this as an upgrade and update or anything other than to be implemented in a warranty repair for a heater failure or broken female glass joint. A unit would have to be rebuilt almost entirely in order to accomplish the incorporation of the Turbulator.
The device is still a handmade Milaana and the units with this improvement won't be available for a few more weeks. Depending on where a retailer is with their supply of Milaana, it may be months instead of weeks until they have units that have this new improvement that was found during Zion R&D and warranty repairs to improve Beta units that have been patiently waiting for Ryan to implement all the improvements he's got in store for Zion.
Perhaps it would have just been best to keep our mouths shut on the Turbulator but transparency helps clarify what is happening, and by having this discussion my hope is that those wanting the latest and greatest improvements understand that these units aren't sitting on a shelf
anywhere right now for sale. The devices are still in testing and final stages of assembly, and we are in the middle of a transition of moving the production from New York to Vermont.
Where the device is now compared to where it was in April 2016 is indeed in a much better place, and that couldn't have been accomplished without the valuable feedback of the FC community and the lessons learned since then.
