OpenHour Gecko TV Box Review | Drops of Wisdom

and here's an excerpt of it:
Gecko has great video quality, and when it plays local content, its one of the best out there for almost (not TS files) any type of video file. But, due to slow network performance both via wired LAN and via wireless (up to 802N 2.4GHz only) connection it simply pose a problem with higher bandwidth (mostly 4K content, but also heavy or large rips of BluRay FullHD content) network playback.
