Hi,
@Wurst , I see from your profile that you are in Germany. Abbott decided to launch it there first, with a view to rolling out across Europe during 2019.
There's an Italian site (there's an English translation) comparing L1 and L2.

The big difference is that L2 has bluetooth built into it, so that you get hypo and hyper alerts (although they are fairly primitive) as the sensor will be pinging readings automatically to the new reader every minute, so the reader will ring or buzz if it's too high or low. You've still got to scan to see results, so it's not proper cgm but many will still find the hypo alerts reassuring, especially at night.
Abbott has also said that with L2, they are going to be calibrating each one individually, instead of in batches, so there are hopes that this might reduce the chances of getting rogue sensors.
The same site has another article, reporting on attempts to get info out of it to work with cgm apps like xdrip+ and spike, which are way more sophisticated than the L2 alerts:

Looks like you may be one of the first posters here to get your hands on one, so we'll look forward to your review of it!
