Rated 4.2 out of 5 by 29 reviewers.
Rated 5 out of 5 by Excellent TV This is a fantastic television for this price range. I had a Samsung 6500 series that I returned proir to purchasing this one and the Panasonic is worlds better. Picture quality, colors, lighting, the remote, smart app speed everything is superior to the Samsung equivalent. I have a 60 inch Panasonic Plasma that I purchased in 07 or 08 that I absolutely love, so no surprise really that this new TV is great too. The one flaw that this TV has is the red light in the bottom left corner, it is very distracting. I covered it with 2.5% tint and that solved the problem (remote still works if tint is used). Panasonic really needs to redesign that but it is an easy enough fix for such a quality set at a great price. March 6, 2016
Rated 5 out of 5 by Another Outstanding TV I have been buying Panasonic TV's since the 1990's and have never been disappointed. This TV is no exception, and the built in Netflix functionality is very simple to use and far more reliable than having to route the connection through another device. I was unable to find Panasonic at any local store here in Northern Virginia (not that I looked that hard), but went on the web site and found exactly what I wanted at an excellent price. I've had no problems in the 2 months it's been in use and don't expect any. February 28, 2016
Rated 5 out of 5 by Great picture This TV has a great picture and we have really enjoyed it. The set up was fairly easy as is using it. The size is perfect for our family room. The picture has sharpness and nice contrast. February 17, 2016
Rated 5 out of 5 by picture quality far exceeds the cost. The depth of the picture is the best feature February 8, 2016
Rated 4 out of 5 by TV looks good. The picture quality is excellent. The price is also competitive as compared to other similar kind of TVs February 8, 2016
Rated 5 out of 5 by I love my TV Great quality picture, perfect size & clear sound. Very easy to use as well. We mounted ours over the fireplace, and it was surprisingly easy to handle even at that height. January 25, 2016
Rated 5 out of 5 by 4K TV deal Great 4K LED. Customer service was great, A++++. I would recommend this tv. I have owned a Panasonic Viera since 2007 as well and still love that one. Great quality. January 11, 2016
