I t Looked into the OTC ones and it does seem they’re binned versions. The failure rate appears to be higher too, which is more acceptable in a non life threatening device.

It also probably gives the companies really valuable data.

You can read the Stelo out into XDrip with some settings adjustments, last I checked, so it is just some “light” software tweaks between sensors.
