Rated 4 out of 5 by from Really Good but Could be Better PROS: I am an associate that works at Walmart in the Electronics department and I always have recommended this sound bar to customers more than any of the others, and that's because this one has great quality. I love all the presets of sound effects that the sound bard offers which helps create different sounds for different things you are watching. I like that the sound bar comes with the optical cable so I don't have to buy one, and since I have a LG tv it works perfectly. I also like that when the sound bar and tv is off and I turn the TV on, the sound bar automatically comes on when the soundbar detects power through the optical cable. CONS: Since I have the LG TV and the sound bar, I have 2 different remotes, the most inconvenient thing is turning the tv on with the tv remote, and then having to switch remotes to mess with the sound, they should make it so you can add the volume controls to the TV remote. If that was applicable for the sound bar, I would have no problems with this sound bar.
