The sound bar arrived in good condition. It was easy and quick to set up: I used the HDMI arc cable provided. The unit improves the sound quality coming from our LG smart TV no end. All frequencies are reproduced better, unless you turn the sound up so high that it distorts the bass. It is now much easier to understand both UK and Foreign tv stations and radio. It is neat sized and unobtrusive. It reproduces music independently from a flash drive quite well. You can also input from Bluetooth independently from the TV, but Bluetooth sound reproduction is not as good.Its functionality is simple so it does not have "rinky dink" surround sound or Dolby etc. It does not support extra speakers or bass woofers but we do not need them. If I need better sound quality I can feed the sound through my HIFI.The unit turns itself on and off via the Arc interface when you switch the TV on or OFF. It's got a remote control.If you require just reasonable quality sound for the money without the "bells and whistle"s then I can recommend it highly.
