I know, I know...get a shield instead. Yes LeEco is a dead company and you won't get any support.
But if you're a gambling person, great set with built in AndroidTV (will forever be stuck at 6.0). It's $349, not $1349, so I'm not super worried about warranties.

For me it's fine, but I was just looking for something that didn't suck and was cheap. Here's my personal opinion on it after 2 months of usage. The exterior design is gorgeous only bested by high end Samsung and Sony. It basically mounts flat to the wall. None of the other cheap brands were remotely this thin or well designed. Not TCL, Hisense, or Vizio.
My wife loves the single remote with built in mic to control everything. People tend to think these things are minor details, but is a huge deal in our family. Whatever chip they have in there has handled all videos I've thrown at it without a hiccup. Previous Nexus Player and returned MiBox stuttered on some shows I had previously recorded on a WMC HTPC. Kodi and Plex work wonderfully on it.
Cons. Dead company. Off angle viewing is mediocre. Has a weird bug that throws the date and time off which messes up the Live Channels guide. I eventually switched to just using the HDHomerun app, so it's fine for me, but be aware of this annoying issue. Has a bunch of weird LeEco apps on the homescreen you can't get rid of. It's annoying as shit.
In short, at $498 (what I bought it for), I thought it was fantastic deal. At $349, it's a steal and in my opinion, no combination of TV + external box remotely comes close in terms of picture quality, value, and design.
Damn, my local one doesn't have one, but the one by work does... I'm tempted to get it just to use it as a regular TV and hook up my Nexus Player to it...
