Excellent product and outstanding performance. Amazon team delivered in time and Panasonic service installed within 4 hours of delivery. Picture quality is amazing especially the 4k resolution. Viewing angle is definitely close to 180 degrees without any reduction in picture quality at extreme angles. The Panasonic app makes remote useless as the tv can be fully operated with it. Amazon prime access on the tv is a great advantage. It makes fire stick and Chromecast useless.
