We bought this to replace an ailing VSB200. This new soundbar has fixed a number of problems with the older unit.

Compared to VSB200/202:
Pros:
More compact, lighter weight
Nice readable display on front panel (textual display indicates input source, numeric volume setting, in the "mute" state, and a small led is lit whenever the unit is on.)
Nicer remote
No more problems with remote IR line-of-sight occlusion (i.e. the remote works every time.)
Remembers input selection even after power is disconnected.

Cons:
Mid and high frequencies are fine, but has very little bass. (Bass is not essential for our needs... But the older bars sounded fuller.)
Increased power consumption. (With average audio content, the 200 averaged about 6 watts, the 202 used 4.5, but this new bar swings between 6.5 and 10 watts. The vizios in general are very efficient.)
More easily driven to distortion than the older/bigger soundbars if you set the bass above '2'.

All in all, the bar does what we need it to do. It is not an audiophile device... but it is much superior to the built in speakers on our ultra thin flat panel TVs.

Update 2013/03/17:
For those who want more bass, I'm told that the Vizio SB4021M-A1 is essentially this bar with a matched external subwoofer.
Also, for those who might have been having trouble with the optical audio cable looseness, I've been using the Belkin AV20000B03 PureAV which seems to fit snugly.

I have been addicted to Vizio since I started to hear about it about a year ago. They consistently bring cheap prices to high end results. This sound bar is NO exception!

Used HDMI cable and could adjust volume through TV remote but the buzzing sound was deafening. Switched to optical cable, buzzing stopped but must use remote that came with it to change volume. Bummer.

I love it. This is my 2nd Visio sound bar. I returned one because I couldn't get it to work on an older SONY. I bought this factory reconditioned unit for a new Samsung 55. I struggled making the optical connection wire (recommended as the best method) to work. I found and removed a plastic blank with a dental pick and needle-nose pliers. Once clear the optical cable worked fine. I like the clear, crisp forward sound much better. For a beautiful TV, Samsung made a big mistake with rear facing speakers.

This thing works great with my LG tv. The optical cable is a must for this unit. It made all the difference

I read several reviews prior to purchasing this sound bar. I does bring the sound forward and has solved the problem of not hearing the sound from the built-in Sony TV speakers. Only complaint I have is that the optical cable doesn't seem to snap in securely. Thus 4 stars; otherwise I would give this product 5 stars. To be completely honest, I don't know if the problem is due to the cable or the sound bar although the cable seems to be well seated into the TV.

This should come with an optical cable. I think it came with the old style audio cables, which most modern tvs don't use as output. I gave it as a gift and they could not use it until they went out and bought an optical cable.

Overall the soundbar works okay. I connected it to an Onkyo subwoofer and that improved the performance a great deal.

My primary complaint is that the soundbar doesn't play nice with my TV remote. It should be against the law for all remotes not to be truly universal. I have a Vizio TV and I expected the TV remote to control the soundbar as well as the TV. Unfortunately the only way that works is to change the input on the soundbar to analog and to change the audio output from the TV to analog variable. I can control the sound levels, but still have to use the soundbar remote to turn it on and off. The optical digital audio works only if I use the remote that came with the soundbar.

It seems odd that Vizio products won't work together. I could understand it if my TV was from a different manufacturer, but Vizio products that won't talk to one another without degrading performance? What's up with that?
