It has yet to be launched. However, with the pivot to data collection, MYDX will need a device to do so. The company has poured extensive resources into its R&D, marketing, etc. That includes the equity costs of locking up IP and manufacturing and, yes, consultants/advisors. They have not discussed the manufacturing of the other sensors in this much detail, they have always remained in preliminary stages. The pen has all the parts needed to be launched now its likely down to the last steps before launch. They expect a small launch in early Summer. Full roll-out after proof of concept and achieving scalability of manufacturing.
