I bought this portable Bluetooth speaker 4 weeks ago , and here are my general reviews for this device. The quality of this bluetooth speaker is beyond expectations. I could hear each and every beat and tone of the song played on this bluetooth speaker very clearly. The bass of the bluetooth speaker is also very good. The build quality is excellent. It dropped two to three times from my hands but it still works perfectly without any issues. The connectivity of this bluetooth speaker is also very good. It pairs instantly with almost any bluetooth enabled device. For this price segment it is a very powerful speaker. However it is not very easy to carry due to his cylindrical shape. So I have to make some adjustments in my bag during travel to carry it. It can be one of the perfect choices for a smart buyer.
