Not small! Not every backpack will fit! Shoulder strap only for carrying. Easy. I want to disassemble to see the batteries, but for now I'll wait 2 weeks. Got pros: It seems to me that 28w is underestimated. He is more powerful. The sight of serious equipment for showing off in front of friends is more like fire! At 2/3 of the volume, the neighbors start pounding into the walls (probably they want it louder). Has some cons: I would like, as in the photo, that each speaker would glow at the same time in different colors. The display does not show the battery charge or I just do not know what to press. There is no charger included. Thank you at least put the wires.
