    Customers like the size of the speakers. They say the soundbar has a tiny footprint, making it easy to place on the TV stand. The subwoofer is slim and easy to hide, and the speakers are small and easily mountable or hidden from view. The sound is good and the sub woofer size is bigger than it looks. The bar fits perfectly underneath the TV between the leg stands.

    Customers are dissatisfied with the connectivity of the speakers. They mention that the subwoofer and starlight speakers often lose connection with the sound bar. The Bluetooth connection fails often, and the SmartCast mobile app rarely works. The sound distortion occurs only on YouTube.

    Customers are dissatisfied with the performance of the speakers. They mention that it never works consistently, the connection fails often, the SmartCast mobile app rarely works, the sound cuts out sometimes, and the hardware buttons on the soundbar itself do not work. The remote works fine. The Bluetooth kinda doesn't work at times and the app is terrible and not particularly responsive. The HDMI connection gave sketchy results with their Samsung TV and the sound bar randomly stopped working with HDMI ARC.

    "...The attachment mechanism doest not work well with the cords and I ended up having to get far more creative than I would have liked to get them..." Read more

    4 Stars
    It's great once you finally get it working right
    This is more like 3.5 stars.This thing was a pain in the ass to setup. I see why everyone had issues with this. To preface everything. I did finally get it working right and it's 100% good every time I turn it on. Here were the problems I had though:- Rear speakers & subwoofer would often not turn on when I turned the unit on- Sometimes the TV wouldn't recognize it and audio would cutI tried so many different things over the span of the first week of having it. Being such an awkward shape and a nightmare to package, I was hoping to fix it and not have to return it. I finally managed to do it, somehow. I have it connected via HDMI ARC. Honestly, I'm not sure what I did. I changed a bunch of audio output settings on the TV and I think that's what finally did it (Samsung 4k JU7100). Whatever it is, it works. I don't have my audio settings on hand but if you ever need them, feel free to reach out and I'll take a picture of it or something. I'll try to remember to add a photo later as well.Anyways, after this is finally up and running, it's the good quality you expect from a Vizio soundbar sound system. One of the best bang for your buck sound you can get. I had an old one before that didn't have HDMI ARC but the sound quality was great, so when it felt like time to upgrade, I got another Vizio. Overall, not disappointed but the frustration in the beginning was definitely disheartening. I can see many others probably didn't have the patience or determination to keep trying and I don't blame them — I almost gave up. It was literally the last thing I could think of trying that got it to work.One annoying thing that is probably IR sensors in general is that this keeps turning on my LED backlighting for the TV, and the LED strip remote keeps turning this thing on/off. lol. Not relevant to the review just an FYI.
