Rated 1 out of 5 by from Disappointed in dysfunctional obsolete product I bought my LG TV, in 2014. I very quickly discovered that the web access is limited. Many streaming services are incompatible with the OS. My TV is now so obsolete that my Cable provider Comcast cannot provide a cable box that is fully compatible. Recently I had to update my Cable box, and I can no longer get quality color on the TV. I've made numerous calls to customer service, and they said they can't help resolve the problem. Comcast has confirmed that my TV is no longer compatible with their current boxes, and they no longer offer the previous one. So I've wasted my money on this TV and in only 6 short years it's become obsolete. Unless LG tries to replace with a new model, I will never buy anything from LG again.

Rated 4 out of 5 by from Wonderful Upgrade We bought this upgrade a similar LG we bought about four years ago. The internet card and wi-fi card failed in the prior model. This new model has a great 4K picture and the ability to access many more internet based applications. While we were unhappy that our prior model had a problem we are very satisfied with this new model.
