As this is my first bluetooth speaker, I have no points of comparison, but I did not find any negative points to raise. - Its ok, without being the perfect sound. In any case it suits me perfectly, especially for the price. - The connection with my Samsung S4 mini is carefree and immediately. - Original design nicely finished and sturdy. - Loading 2-3h for holding 7-8am listening. As against the usb charging cable is very short (10-15 cm), but with a USB extension cord directly to the desktop it does not bother me at all. - Ability to pause and change tracks via a long press of the volume buttons. - I have not tested the calls through the speaker, but this function does not interest me (yet). - Support still young, but very responsive and attentive ( [email protected] ): I had a question and a request for the electronic version of the manual and I had a very fast response and manual mail.
