My one month of test and experience says that the best speaker in market for 1000 rs. its audio quality is compare to sony’s portable bluetooth speaker and even the loudness is higher than the sony one. But one thing keep this thing out of reach of water because its metal part get rusted after getting contacted with water. It has good battery backup about 4 to 5 hrs of music play. I am a regular user of this speaker and it feel light and handy and I recomended this to those who love music and travel a lot.
