    Pioneer 70 inch Roku 4K TV

    Awesome TV wish I would’ve bought it sooner… Easy to set up easily programmable. The foot stands that came with it were a little wider than I had planned so I had to buy another stand for it. Otherwise, great picture, quality, lightweight, and easy to handle…. Would definitely recommend..

    Excellent picture. Great value for the money spent

    Easy setup, easy remote, beautiful picture quality and best value I’ve seen in awhile! The only improvement would be the audio quality for the built in speakers. Not as robust as other TV’s. A sound bar fixed that!

    Unbeatable picture quality and unbeatable value

    Excellent smart television with the trusted and easy to navigate Roku operating menu. Before purchasing, I looked in store at all the other larger screen (70 inches and above) and there was no comparisons between screen resolution, color science, and the finish of the Pioneer HDR ROKU smart television! It was not only one of the best values in the store, but also an excellent value
