We have the 55" version of this and love it. Probably the best value out there for a 4K HDR set. The local dimming can cause occasional weirdness (most noticable on the spinning loading ring) but the apps are all chromecast on the back end with lightweight frontends created and updated by Vizio. We’ve gotten a couple of firmware updates over the last year as well. 4K from Netflix (stranger things for example) looks stunning. I would highly recommend this TV if you’re in the market for one. It consistently got/gets great reviews from all over the net as well.
