Rated 3 out of 5 by from the product is too complex Given the BT you view input, the handling of the various features and apps is rather confusing as one has to handle three devices in order to reach all TV and Internet applications which the set offers.

Rated 2 out of 5 by from High tech but missing basic apps The tv itself does not lack in picture quality or physical design. For a product that boasts about so many technologically advanced features, I was extremely disappointed to find out it had already fallen behind in terms of apps. One of the main reasons I bought this TV was to be able to use apps such as bbc iplayer and Netflix, which I thought would be a basic thing for a 'smart' TV to have access to. However I was wrong, this TV is already outdated because of licensing laws which has led me to be mis-sold a product that I thought was advanced.
