Since I could make 1 good experience already with JBL standing speakers and Control I had decided on this portable solution. I use the speaker now quite a few years and am very satisfied. The sound quality and volume are Baßvolumen wirlklich TOP for a product of this size. Compared to some other speakers always astonished eyes of their owners came. The persistence with good batteries is truly outstanding. With the compact power adapter, the sound is a little louder, but for this reason never necessary. The workmanship is very good. I do not know how many times the part is already fallen down and it works like at the beginning. The optics has suffered somewhat with time. Grains of sand from the beach've already left some scratches on the cover.
My recommendation par excellence - do not miss the part!
