I think I would upgrade from the Vizio 2.1 soundbar , which perform well . my first vht510 last about three week before the blue volume , etc. , led stop work . the sound quality , in my opinion , be spectacular for the price . because the indicator light provide the only visual feedback for the various setting available , I return the unit to Amazon . the replacement unit work perfectly when I set it up . however , when I turn the unit on the next morning , I find that the subwoofer lead indicate it be not connect to the sound bar . the soundbar 's wireless function appear to have fail . two different Vizio technician be unable to to correct the issue over the phone . since this be a replacement unit from Amazon , I decide to send the defective unit to Vizio in hope that whatever problem be associate with the unit will have be correct in its replacement . we 'll see !
