I got a 4K TV by accident. I ordered the 1080p version of Vizio and got the 4K version by mistake. Best Buy took care of the price difference, but I returned the Vizio and bought an LG 4K instead.
I wanted to like the Mi Box. I really did. I didn't want to move my Shield TV, as it is hooked up to my 1080p TV in my game room, and all I needed the Mi Box to do was deliver 4K Netflix and YouTube.
It's the little things. Like, It doesn't always wake with my Harmony Remote. In fact, it almost never did. No change to the power settings made it work reliably.
It also doesn't work with a USB Ethernet adapter. At least not well. I have a rock solid WiFi network so the Mi Box always gets at least 100Mbps, usually closer to 150 on every fast.com speed test. Plug in a USB Ethernet adapter and no speed test hits above 10Mbps.
There is also the lack of a play/pause button or even command for the Harmony. The center button is fine in most cases, but some apps require the command.
There's also the Vudu issue. I have Gigabit internet, and on every other device in my house Vudu (and every other streaming app) just screams. Vudu looks amazing. Everywhere but the Mi Box. The video stutters in every single video that we stream. It's so noticeable that my 4 year old sees it. Nonstop stuttering. Non. Stop.
And then YouTube. The Mi Box cannot deliver 4K video in the YouTube app. It pulls up short every single time. Most 4K videos play in 1080p, but some play in whatever resolution falls between 4K and 1080p. And every single 1080p 60fps video skips, stutters and buffers until you stop watching in frustration.
The new Shield TV in the same spot as the Mi Box, using the same Ethernet cable that was at one time hooked up to the Mi Box is killing it. Not a single stutter or skip in Vudu. 4K YouTube and Netflix titles are playing in 4K. No skips. No stutters.
The Mi Box is now hooked up to our home office TV. If it can't do the job in there, I'll put it in a drawer somewhere.
tl;dr too many drawbacks to the Mi Box. Replaced it with a second Shield TV for 4K. Got the Best Buy surprise remote in the box package. I had no idea they were doing that.
