This is Amazon's newest model of their premium Omni Series TVs.
Brad's Deals Editor Michael,
The Amazon Fire TV 65" Omni QLED Series 4K HDR Smart TV drops from $799.99 to $549.99 with free shipping at Amazon. This matches the lowest price this TV has dropped to since its launch earlier last year. The Omni Series TVs have a built-in Amazon Echo that lets you control the TV and other smart home devices using Alexa commands. They can also be used for two-way video calls to other Alexa devices when you pair them with a webcam.
