Nearly perfect! 22

Benefits:
+ Small (B: 18 / T: 5 / H: 6 cm)
+ Many connectivity options (Bluetooth, USB, Micro SD, AUX IN)
+ FM Radio
+ Super sound (Of course, no party speaker, but for the price perfectly)

Neutral:
No +/- mode selector switch
+/- Phone Speakerphone (wenns who needs, I do not habs tried)

Disadvantages:
- Touch volume control some getting used to and "hakelig"
- Built-in battery fix
- Mini USB charging port as (Micro USB, as in today's cell phones would be more practical)
- No folder or Schuffle function when playing from a USB flash drive (this feature very limited one)

Compared I have the Dolcer AirNotes even with the 2nd Gen EasyAcc® Olive, who has the same feature set. But the EasyAcc® 2nd Gen Olive comes sonically not to Dolcer AirNotes zoom!

Conclusion: Buy recommendation, for the price does not go wrong!

Supplement for charging the device:
LED red = -> device and loads
LED = purple -> device and loads
LED = unlit - loaded> completed
Basically, the device can also be charged during operation, but partly, I realized that it is the touch operation may not function properly. So who has problems with the operation, just unplug charging cable!
