Rated 5 out of 5 by from Lg surround sound We totally enjoy the product. We were let down by the installers and I was threatening to take it all back. I'm glad I didn't since it has been installed we love the sound and features. We would never go back to just using the tv speakers.

Rated 4 out of 5 by from home cinema system Easy to set up,easy to use good picture quality. Could do with longer speaker wire for front speaker's and maybe small speaker mats for rear speaker's for sitting on wooden sideboard.

Rated 5 out of 5 by from A great television I bought this smart television to replace my old one. The picture quality is superb and the new bluray player with cinema souround sound I bought to go with it makes viewing a whole new experience. As a player the set up is easy and there are so many options you can change. The souround sound is amazing. Watching an old war film the other night, I thought I was back in London during the blitz, with bombs dropping all around me All in all, I highly recomend it

Rated 1 out of 5 by from A very frustrating piece of equipment I definitely could not recommend this home cinema to anyone. It is very complex, even for someone who has a good basic knowledge of how to set these things up. Many people must have given up without achieving a satisfactory set-up. It failed consistently to recognise the optical input from an LG TV, does not recognise the Smart handset (wand type) and to be brutally honest, the sound quality is not worthy of this price bracket. It won't be very long before I cut my losses, throw this in the skip and start again with another brand.
