Worth asking _what_ “FREESTYLE LIBRE CONTINUOUS GLUCOSE MONITORING SYSTEM” they mean, since there are at least 5 different ones, I think. ATM Abbott are listing the “Libre 2” and “Libre 3” plus the “Libre Duo” as “coming soon”. The latter is the one with the blood ketone measurements. Both the numbered Libres come in “original” and “plus” flavours.

I’m trying to get the Libre 3+ now; I just talked to my endo about a swap from the G7 (10 day in my case) to the 3+, but I’m on Medicare of course so that should not be a problem, or will it?

My opinion on forced swaps caused by insurance is that the best approach is to do it now; ASAP and keep hold of the traditional diabetic squirrel stock of the old stuff. That way if the new stuff doesn’t work we have a stock of old stuff while the appeal is in progress. More than that the insurer can’t require “step therapy”, or whatever they call that variety of a PiP, because it’s already been done.

Assuming you do sign up with Abbott _use the **Libre** app_; it supports all the current sensors whereas there are [credible reports](https://forum.fudiabetes.org/t/possible-libre-bug) of bugs in the other apps resulting in lost sensors (they get replaced but that’s always tedious).

If you choose the Duo watch out for app problems…

The app compatibility seems to be lazily enforced; some of the tech bro products we use simply refuse to run on any 'phone they don’t recognise (or is it, “Get paid to support, directly or indirectly?”) I was able to install the app, which I shall call Liberace since that seems inappropriate, on my 'phone with only a minor whine. I’ve yet to get any sensors so I’m going to have to wait to experience total systems meltdown. Nevertheless I live in hope.
