"For the price you can't beat it!."4.0 starson by Jhon70
Pros: Ability to program soundbar with your TV's remote control.
3 gain selections on soundbar to help boost the sound.
Wireless subwoofer does not have to be line of sight like Vizios.
Cons: Some think it's not having a HDMI input,or an optical input.All I know is with the RCA plugs(red and white) connected it sounds good to me when you set it all up for PCM,especially the price which WalMart rolled back to $198.00.
Summary: If you need one with an optical input you can go to the Best Buy website or the Polk Website and get one that's higher priced.But for $198.00 from WalMart I think Polk has a winner.Just make sure you setup everything for PCM and Dolby Surround Sound.Forgot to add when I received this unit it came with it's own individual remote control,also 5' RCA cables.

To see if it's increasing or decreasing the volume there is a little green LED that blinks when you try to increase or decrease the volume.
