That’s great, Franz!
I recently got my second Motion B and having them connected using True Stereo is a great experience (even though the Motion B’s bass response is pretty lacking).
Happy to hear that you got a second Flare…something that you’ll get some great enjoyment out of. 
YEAH! That’s great. I’m listening to my stereo paired Icons right now! It is AMAZING!!! Congratulations @Chiquinho
In a little over a week I should be listening to stereo paired icon+!!
Awesome glad to hear!
The FLARE got power for about 8 hours when played pretty loud.
Thats quite a lot.
And the kids will learn : Not charged : no music! 
There is a lot of “play around” to find an optimal place for the speakers.
I put them in the corners of the window in front of my writing desk.
The FLARE has 360° radiation.
This feature has to be mentioned.
And last not least .
Another place needs another eq adjustments.
Crazy!
Also: Not charged, no recharge! (in regards to an external power bank)
