I had this bar for a few weeks. Problem is the blue led lights that indicate volume change and eq settings go out on them. The LED failure rate is high. I'd guess hundreds hell maybe even thousands of bad units. Who knows but Vizio refuses to acknowledge it as a real problem. Basically saying shit happens and not all of them fail. My local Costco said they pulled the remaining stock off the floor because of all the returns.
Otherwise it does sound good for what it is. I'd only put the JVC BA-3 ahead of it in the limited 5.1 soundbar market. The JVC has its own failure problems as well. Ended up returning both 5.1 bars after they failed within the first week of owning them.
