I have the GC variant, and while it's a 'swell tablet it isn't without its issues. For instance the Kitkat firmware that came with some units tends to have a rather unresponsive touchscreen at times, necessitating an upgrade to Lollipop. Problem is some regions don't receive the latest firmware via OTA, so I was practically forced to flash an SP Flash Tool image instead.
You can find an SPFT package of the GC variant here:
