100% more Flighttime? What do you think of the NEW Noro-Ion flight batteries?

Hello fellow RC flying enthusiasts. What do you think of the new Noro-Ion flight batteries? Or in other words, what`s your experience with them? I managed to get over 15 minutes of flight time with my Blade 230S microheli UH-1 scale heli. With LiPos, the maximum was 6–8 minutes. So I`m happy for now. Has anyone else had experience with scale heli flying using these new Li-Ion cells?
