Major Selling Point: Special Amazon Fire TV Edition interface.


Maybe one of the best 49-inch 1080p HDTV with smart feature made by Amazon. Gets the value and features on what you paid for but I wish it was 2160p (4K) instead of only 1080p resolution because that the only feature it lacks to make this a perfect HDTV for your home use.
