Remote only illuminated 1/2 despite new batteries. Could not get rear speakers to work properly despite following instructions step by step. Bluetooth never did work properly. I tried HDMI, tried Optic Cable and read instructions again. Lights on front of sound surround worked once and never again. Just a bad experience. Bose did pay for return shipping. I purchased a different manufacture sound surround and it works perfectly. So disappointed in this Bose system.
