This box is great, and delivery was fast.
The seller is very helpful with any problems you may have, and they reply very fast.
XBMC is now renamed to Kodi, when you get the box you should update Kodi to the latest version.
This is easy to do. just go to the Kodi website for the update and instructions.
Firmware Update Files... The TV Box are now being sent out with the latest Firmware files Pre-installed, so no updated files are needed.
The only problem I have come across was when playing HD Video they would sometimes play back on a tiny screen.
And sometime the screen would be blank when playing video but you could still hear the audio.
I have found that if you disable HDMI Auto setting and lower the display setting one notch down (in android not XBMC/Kodi) the Videos will play back in the full size screen the way they should. This does not degrade the picture quality enough that you would notice.
I have read this is to do with the Amlogic S805 chip, and is a known fault with xbmc/kodi, with luck this will be fixed in a later update. This problem is on all of the boxes no matter what brand or model with the Amlogic S805 chips.
Hope this is of help, and if you need any help setting Kodi up my advice would be to read the help pages online and videos on youtube.
I found totalxbmc website (type it into google) to be one of the best and easiest to follow. But there is loads of others.
You will soon find all you need to know.
If you are also looking for a small remote size keyboard and touch pad, I recommend this one on Amazon as it works great and allows full control of the box....eSynic® KB04 2.4G Mini Wireless XBMC Keyboard Touchpad Mouse Combo - Multi-media Portable Handheld - for PC Andriod TV Box Media Mini TV PC Stick HTPC Laptop Xbox 360 PS3- British Layout-Black Color
