I have the 4K stick. Feels a bit faster than the MiBox. Remote has not disconnected yet, just had the wakeup issue while it was still on the old TV without CEC. Only had it for a week or 2 so cannot comment on overheating.That is not the 1080p version, that is the 4K version, it should be more than a little faster than the Mi-Box, as for remote disconnections, or overheating ... , I don't know. Still want to get one ... , or another Fire TV 4K MAX stick.
