The performance of this speaker is impressive for its size, the more it looks solid. Nevertheless Tweetter it (which retransmits the treble) tends to saturate if the sound is maximum. Then the voice guidance is particularly (boring) stressful, but you can remove it by turning off the enclosure and pressing the - button at the same time you turn on the speaker then release the button - when you hear a sound. Finally it sits well in the hand and its design is neat. Try it and adopt it !!
