They completely kept their word during that indiegogo project. I received 2 units actually and have kept one in the plastic as an iconic MJ legalization sign of the times for when I'm old and grey lol. A prohibition era collectors item if you will.
The MyDx2 unit and AquaDx are supposed to be launching this month from what I have read in the recent past. That is what I believe the 8-k is about today. The new unit will use a different sensor technology. It wont be NDT's polymer films but will instead be enzyme based sensors in this upcoming iteration of the device.
A separate CannaDx2 unit is supposed to follow MyDx2 but no details on what that will be like yet. I believe they want to be able to sell the food, water, air device separately from MJ for an easier time with global sales. Although the OrganaDx(food) sensor can also detect pesticides in MJ.
