Nutek Bluetooth Speaker System: Bring the excitement to your next gathering with this speaker, which comes with a microphone that lets you sing along or make announcements. Bluetooth allows you to wirelessly stream tunes from a compatible phone, tablet or other device.
I ordered one and charged it as indicated in the manual. Worked great when it was plugged into the wall. When you unplug from the wall, the first time you play by bluetooth or auxillary work fines, but turn the machine off and try to play through these ports again and there is no sound. When you plug back into the wall, all works great. Called Best Buy and they graciously sent another. The same issue on the second unit. I e-mailed the manufacturer and the only response was return to Best Buy. I returned and got my money back! Speaker and disco ball are great, but when you buy a portable speaker the point is to play without plugging into the wall.
