An update needs to be provided by Uncle Tom to highlight that the Vizio M51a-H6 has a VERY HIGH rate of fatal failure and that Vizio is no longer providing warranty replacements, only refunds.
Costco and Sams are still taking these defective bricks back as returns, but there is no guarantee this will continue. Costco is still selling this model, but consumers should stay away and buy a more reliable system.
This product sounds wonderful, I absolutely love the sound, while it worked I should say. My failure rate on 2 of these systems was <6 months, other consumers have had failures between 1 -6 months and that is disappointing.
