A brief update on the #Simplera now that I'm three days into using it.
Whilst I haven't been closely tracking proximity to fingerpricks, I've done the occasional "soft calibration".
The Dexcom ONE that went on at the same time appears to be tracking more closely.

The Simplera is regularly between 0.5mmol and 1.5mmol lower than the Dexcom ONE. At the current readings, it's a bit over 18% lower.
This sensor has been consistently low, but this is n=1.
The sensor is susceptible to compression lows, just like the ONE.

Let's talk about the app. The black background with white CGM trace & numerals are likely to be easier to see if you have vision problems, but the constant vertical axis set to the full range of the sensor, with no ability to reduce it, will annoy some.
Firstly, it seems that CKMs are prone to the same compression problems as CGMs, which should be no real surprise. You can see this here overnight where readings are lost. /2
From a measurement perspective, values are noticeably different with ketones present. The blood tends to be considerably higher than the sensor reads. /3
After two weeks, the #BattleRoyale (an n=1 comparison) for CGM is done. And there's clear water between the three sensors being tested, which were the Dexcom G6 & G7, plus the #Libre3. What follows is a brief summary of the results. /1
First up, the consensus error grids for all three sensors. Firstly, the Dexcom G6:
