    Product works okay, much better than the tv speakers. make sure that template for wall mount is very tight, no wrinkles. very little tolerance for mounts. Set up works okay but sound sounds different. Still working on settings to make sound right for large room. Cords for speakers are very long, have to buy new ones to not have excess laying around.

    Don't waste your money on more expensive systems if sound quality is what you're looking for. This system sounds great and the price was right.

    When you first listen to your new Vizio sound system you can’t help but be amazed at how great they sound, and you reflect on what a great deal it is...BUT....these do not last. This is the third and LAST Vizio sound bar I will ever buy! All three sound bars worked great for 1 to 2 years, then they stop without warning just like you pulled the power cord out. When the second one died I called customer service to ask if there was any kind of a fuse that might have blown. It was like talking to someone who never saw a sound system in his life. I had to tell him how it worked! Bottom line, no replacement parts. - Like a fool, I bought the same one again since the bass & satellite speakers still work great...why throw away perfectly good speakers. Anyway, this last one just stopped working today after 1 year 4 months. I still have the extra speaker in the original box. Arrrrr! For the price of 3 Vizio sound systems in four and a half years I could have bought one really nice high-end system that would still be working today. - Live and learn...

    Usually TV manufacturers are good at TV's but not so great at sound, especially with the mini-speakers located in the TV. I read good reviews on the Vizio sound bars and thought I'd give them a tray. connectivity was easy and I was surprised at how good they really sound. Even my wife commented on how good they sounded. Maybe not Bose quality sound, but excellent sound for less than 1/3 the price. Well worth the price.

    Bought it on sale and I'm glad I purchased this sound system. The sound is crisp and clear, and bluetooth connectivity to the apps on the phone and to the television is very simple! The wires for the satellite speakers are a bit much, but the great sound makes up for it. It has the standard sound outputs like RCA, coaxial, Optical, and HDMI. I was able to connect my PS4 to the sound system using the HDMI out to the HDMI-ARC on my television. Gaming and watching blu-rays and Netflix is awesome on this sound system!

    This is a really nice system. Beyond the price, this is really nice! It is very powerful and you can not go near full power with out hurting your ears. The sound is rich and clear. It really creates a nice surround sound. I now hear things that before I didn't know was there from my TV even though I have a pretty good plasma. I would recommend this product and I don't think you will be disappointed. I am very happy with it and we have used it with our TV, old VCR, Bluethooth. Plenty of cables to make it all work.

    My husband and I purchased this sound bar after receiving some unexpected gift card. We did not research much but the sales man pointed us in this direction due to what we were looking for. Happy overall, the sound quality is great and what we expected. The only downfall is this helps height of the bar. It sits in front of our TV and blocks the sensor, which in turn makes it a little more difficult to turn TV on or use the remote. Not a huge deal, I would purchase again.

    Simply Amazing

    First, I was very happy with the Best Buy service, the person who assisted me, helped me, he looked for the product and even gave me the lowest price Costco had. Excellent service. Second, the product simply amazing, I have read many comments about this product and here at Best Buy had very good comments, which I am confirming today. There are also some bad reviews, but most of them are for defective products, well I had good luck to this day. Quick installation on the wall, Installation via HDMI (ARC). Simple configuration on my Samsumg tv, subwoofer detected immediately, it was not necessary to do anything, nor with the rear speakers. Sound more than expected and very satisfied by this purchase. As said another comment disable the DTS TruVolume happens to be a spectacular sound. Wi-Fi configured (link option ON) and installed the latest firmware version. After, no problem to configure the SmartCast APP, many say it does not work, I confirm that there is no problem, by the way with this application it is easier to control all the settings of the Sound bar, which with the remote is a bit uncomfortable. Used Iphone 7. TuneIn Radio, Pandora tested and phenomenal sound, bad news for those of Spotify does not work yet. But this seems like Spotify's problem. Youtube, Netflix, and my Blueray connected to the TV, I did not to do anything all works fine, just with my HDMI connection (ARC). Another tip: I tried to put another HDMI cable gold tip did not work, I had to use the one provided by Vizio. Finally I am using the CEC function of my samsung TV and everything goes on and off at the same time, also this function works very well. My children were very surprised and my wife was pleased with this new member of the family. Just waiting for more family and friends to arrive for these Christmas dates and be able to boast this my new toy.
