I agree with the above, while worth watching, best to exercise a caveat emptor approach. One of the the caveats is you will need the MarketEnabler_v3.apk to change the settings from the default ( Chinese ) to another region. On the other hand the ug802's and 808's get excellent reviews on 1080p playback.
Getting the content to them may be wired only, especially for high bitrate. If you use the .apk, don't forget to clear the google play app cache and data.
