Product excellent, very good sound, even very strong no sizzle. A little hard to pair it at first, but if you do not know the make or if you have any doubt, do not hesitate to call the manufacturer who will answer the phone very quickly and give you all the explanations required for proper operation. This speaker is rechargeable in just about 3 hours. It works for more than 8 hours to half power and still preserves the battery for the next time. Malgrés raise raising its price, it's really worth. This is really a high portable speaker that you can really take anywhere, any wire or cord necessary bitch to her bluetooth function, it is very convenient. The carrying case is TRSE practice, it prevents dust from getting on the speaker. I recommend this product to all nomadic or sedentary who loves even take their music in a different room of their house or even those who like to listen to their music outdoors. Really great product. Sends very fast and well protected packaging, no risk of breakage upon arrival. Really do not hesitate, it's a very, very good speaker!
