I'm one of the few client here in France for a few days. I moved from Paris to a quite isolated area (Vercors mountains) with only ADSL (no mobile coverage), and it's night and day, I now get between 100 Mbps and 200 mbps with 30/40 ms latency...
I don't have a lot of time with the service to give an exhaustive feedback, but for the moment I'm able to do video conferencing and call perfectly. And the setup experience is great!
