The only negative points are the charging plug, which unfortunately is rather jack USB on the unit. (Which also is not an option to use it as directly as other USB speakers to the notebook available.)
And the second point is that the Skip buttons are used twice with volume and thus no coils in the track is possible.
For longer audiobook tracks can disturb.
But definitely a buy recommendation (eg if you have a backup solution for the bathtub or in the kitchen needed) bottom line.
