(I really wished they made an 85" when I was in the market a couple of years ago, instead I bought a TV from Costco and opened it up and disconnected the WiFi module before powering it up for the first time.)
They tend to last all of about two months, in my personal experience.
Counter-anecdote: I've had a Sceptre one for about three years, zero issues. It was the 65" 4K, it cost about $500 at the time.
