The speaker is excellent for its price.Completely Surprised with the sound output it produces for the speaker below 1000 price tag.. Here are some Pros and Cons PROS: 1) Volume even at highest is very decent. But advising not to use in full volume continuously as the volume may burp eventually by using continuously at full volume. 2) Bluetooth, Aux jack, TF Card and USB connectivity is very simple. 3)Build Quality is superb and design is compact. 4) Good bass in the segment of this price range speakers. 5) Radio is ok. 6)Battery lasts for 4-5hours on USB/BT mode with 75%volume. 7)LED type colorful lights looks very attractive. 8)********VERY IMPORTANT******************** For those who say FM is not working..Just Use charging cable(Provided in the box) as antenna while in FM Mode and see the difference.All the channels are detected and FM too works very cool. CONS: The cons are not that serious but still for the sake of information: 1) AUX cable provided is of average quality which leads to less than average sound output from the speaker(Suggest to use Good quality AUX cable for better result) 2)No indicator for charging completed indication. It keeps on charging(Shows red led on).But this is not that serious issue as 3 hours charging is sufficient for 100%battery.You can check battery status in any mobile having B- 5C battery(Nokia mobiles mostly). 3)The surface of the speaker is bit slippery so it may slip from the hands.(But no compromise on build quality) If you are looking for speaker with all basic facilities and that too under 1000 range then go for it.. The only substitute for it in terms of crisp and clear sound is "Portronics Pure sound"(But it has no Bluetooth connectivity) On concluding,I would like to suggest to go for it and enjoy the Chota Package,Bada Dhamaaka!!!!!!!
