As a current user of a Dexcom and a future user of a Dario, all CGMs currently on the market require calibration every 12 hours, so the BGM market is not disappearing any time soon.
Dexcom is not a competition to this product, since as I'm sure you know that the Dexcom is a CGM, and the Dario is not. I spoke to Dario a while back concerning the ability to upload Dexcom data using their cloud platform. and auto calibration from the iPhone app to the dexcom. they were non-committal other than saying that it is not a bad idea but they have some maturing to do before they can consider the integration of other platforms.
I would like FDA approval since I'd like to use the product, I'm now using the Vario and it can be up to 20% off in the results, that affects my insulin dosing which in turn can cause hypoglycemia. 99% accuracy would be great! As an investor, FDA clearance would probably make me a bit of $$$ so there are the two benefits for me.
You are correct, however Tandem should be the first since they actually built the T:slim with G5 integration in mind and thus included a Bluetooth receiver in the current non-G4 version, though it is disabled. I assume it will require a firmware upgrade. The issue will be FDA clearance for the release of the upgrade. I don't know of any consumer based medical devices that allow a firmware upgrade for updating a feature set.
Perhaps the people are awaiting the G5 integration before purchasing. Why go with a G4 integrated pump when Dexcom has released the G5?
Nice, but is speculation at best. But I do see $1 about four to six weeks after FDA clearance.
If they use their software platform to accept data streams from other devices such as the Dexcom, and pumps then I think there would be an incentive to user their system. currently each system (CGM, Glucose monitor, and Pumps) has their own app for tracking and correlating the data. One app that could easily combine these disparate but related data streams would be a compelling case.
You are absolutely correct, it's not only the coolness factor but it is easier to use than most others.
