Seems no one read either the box or the directions before installing this. It's stupid simple and works perfectly with my 47" LG TV. Hook it up to your TV, plug it into the outlet, turn on your TV, change your audio settings for external output via the recognized Vizio soundbar, and voila! it works. Remote works just fine, too, but it's not needed since it integrates with both my TV and cable remote. The sound quality is just as advertised -- a nice deep bass for movies and music and stereo for dialogue. No need for a subwoofer and it will blast the room full of sound! I would definitely recommend, as this is a high quality sound bar for the price.

Update 7/30/2014:
Wanted to post a quick update for a couple reasons. First, I just wanted to say that I've had the 38" soundbar for about 8 months now, and it's still going strong. In fact, I like it so much that I just purchased the 29" version for my smaller bedroom TV, and it works just as well.

I also wanted to quickly address some of the negative reviews I've seen. Nothing frustrates me more than seeing someone give a product a low rating simply because they are using it improperly or otherwise have unrealistic expectations. I noticed one review where the person complained that the sound bar can't be connected to a receiver, but rather is meant to hook up to the TV directly. A couple others complain that the sound is out of sync when both the TV speakers and soundbar are turned on. Both of these issues stem from the same place, and that is an apparent lack of understanding of the fact that A SOUNDBAR IS SUPPOSED TO REPLACE YOUR TV'S SPEAKERS. That is its sole purpose in life (along with streaming music via Bluetooth, if desired). The instructions even state that you should connect the soundbar to your TV, then change your settings to disable the TV's built-in (and assuredly terrible) speakers. They are not meant to work in unison. This unit is not meant to hook up to a receiver or otherwise be part of some complicated chain. The soundbar plugs into the TV, and the audio that used to come out of your crappy TV speakers now comes out of this sleek, great-sounding unit instead. End of story, and rant.

Original Review:
Bought this for use with a 52" LG HDTV. The funny thing is that I've noticed several reviewers complaining that their Vizio TV remotes don't work with the soundbar, but I discovered quite by accident that my LG remote does.

If you are considering this product you probably fall into the category of needing space, want something to look cool, and above all sound good. With this price point leave the expectations a bose cinemate experience. In a 20x20-ish room this will fill easily. The 96db rating that the manufacturer gives isn't a typical number people wrap their heads around and hard to compare competition with watt numbers. After some digging, I believe it is above 100 watts. Many at this price point is more like 60 watts. (but note that 60 watts is not half the volume of 130. Wattage continues to be a marketing tool to impress the consumer with big numbers. It is not one to one ratio with volume)

I paired this bar with one of Samsung's led the (6300 series) and as sleek as it was, the sound is bad. I mean it is anemic as its form factor. And if you have one and you don't think it's bad, then you will be blown away when you hear this bar.

Okay sound. It is crisp. Compared to lets say the typical sony bar, which is bass oriented, but muffled. The integrated deep bass that this bar is talking about, think more of the similar if not the same technology as the bose sound link blue tooth devices. (which is amazing for its size by the way) It gives warmth and body to make the sound feel whole. It especially is convincing in movies and dialogue. It allows for separate bass and treble adjustments, but realistically: you won't want to take the bass less than its maximum, and maybe treble you may want to go anywhere from its max to maybe 2 steps down if you find it to sharp. It has simulated surround which works well. Bluetooth pairing was a cinch. I didn't like it for music as much but it's okay.

I bought this to replace a VIZIO SB4021M-B1 40-Inch 2.1 Home Theater Sound Bar with Wireless Subwoofer that fried itself a couple weeks ago. I thought about buying a different brand but it's hard to beat Vizio on price and features, and I've generally had good luck with their products (the fried sound bar being the only exception). Here's my thoughts:

+ Good treble and mid-range sound
+ Looks nice. Not flashy and blends in with my TV.
+ Bluetooth pairing is easy and works great for listening to podcasts or music from my tablet
+ Good price

- No screen to tell you volume level, input selected, etc. Just a row of lights that blink in different ways to serve about a hundred different purposes. My old sound bar had a small screen in the middle and I had no idea I would miss it so much.
- Doesn't turn itself off after X minutes of inactivity.
- There's really no "deep bass" to speak of. The sound is good, but for a fuller experience you'll want to add a subwoofer.

Overall it's a good product for the money, but if I could do it over again I would probably buy the SB4021M again. It costs more but is worth it.
