To answer a few of these questions, I've spoken to various people at Medtrum over the past 18 months or so, so let's see what we can take away from this:
Conversations with various Medtrum people indicate that the sensors are restartable, so very much in line with what we all do with the current Dexcom sensors (note that this doesn't appear possible with the G6). Again, I'll feedback on that when I get to it.
Across all data, the Mean VfD (ie the directional average rather than the average of absolute values) for the A6 is 7.0% versus 0.1% for the G5, which means that there is a significant skew to over reporting the value and therefore causing people to treat a non-existent higher value and risk hypoing. This is most pronounced effects are in the first three days of data. The 4th is more aligned with the Dexcom's variance.
The ordering process is a little annoying, I'll give you that...
The sensors are warrantied for 7 days. In the app it says they have x/7 left to run. When we get to Monday I'll see what the 14 day option does.One other interesting factoid is the 7 or 14 day usage mentioned above. I asked about this and she explained that each sensor will only last for 7 days (half the life of a Libre sensor). However, you can choose whether the transmitter will run for 7 or 14 days.

This one is interesting. For me so far, there are two clear phases on the sensor. Days 1-3 and day 4 onwards.I am very curious to see whether the Medtrum varies in accuracy over the life of the sensor, because that is exactly what happens to me, with the Libre, which is most accurate between days 3 and 13 of the sensor life.
- Days 1-3 have really bad Mean Absolute Variation from Blood (VfB), as the article shows, and perhaps more disconcerting is that the Mean VfB is skewed heavily to overestimating levels.
- Day 4 showed a marked calming in the sensor's response, and I'll be keeping an eye on it. Yesterday the values showed a Mean VfB of around 8.8%, in line with the manufacturer's stated MARD, compared to the Dexcom's 7.8%
