Worst product ever I purchased. the main problem is when sound increase aux as well as bluetooth disconnect. . like switching the thing again and again . the main issue is no service centre for this product is available here. I have very bad experience with yhis product. the speaker quality for this product is very bad . the main part is one side of the speaker has sound but the another portion of the speaker is blunk. no bass at all .i used the item only for 3 weeks. bery bad product . do not purchase.
