Go value for the money


A month is not really long enough to give a good review. TV works as it should do and has a very clear picture. It will be interesting to see how well it works in two or three years time

Great looking TV with decent sound quality


Went to purchase a Samsung but the one i wanted was sold out. However, I then looked at this Sony and was impressed with the build quality along with picture and sound quality. To sum up, glad the Samsung was sold out!

Nice Telly


Got this telly about a month ago. It was to replace a 36 inch and due to limited space it is slightly larger than i wanted but just fits in. I am pleased with the picture quality.
