Product Review; "This speaker absolutely bumps! It can easily fill a large room with great sounding music - Unfortunately no volume control on my model, so be sure levels are correct on the playback device before you begin. Bluetooth connection is good at about 10-20 feet, especially with the lid open and antenna up. The battery is massive, lasting easily a week or two of moderate use, and the included USB ports for charging other devices is a huge plus. It is quite expensive (usually about $400) but look for it on a holiday sale and it's a fantastic quality speaker guaranteed to last."
