The advert ways 4.2 but it comes with 4.4.Yes
The dual-core sticks are quite snappy, 40 sec to boot to Android desktop.
You also get ones with female HDMI ports, so you can connect a HDMI cable to it and it doesn't plug directly into the HDMI port if you want to move it around for better wifi signal or plug a USB Hub into it, so it doesn't hang from the HDMI port of the TV.
Every device has it's own serial number unlike the AMLogic ones.
Don't know it that has been fixed yet.
Just make sure you buy one with KitKat firmware.
With Mediatek or Realtek wifi.
Look on freaktab forum for names with custom roms and KitKat firmware.
All these sticks also have different wifi, so different device firmware is cross-compatible but wifi won't work.
But you can build your own firmware if needed and you get the correct wifi pin numbers.
KitKat isn't the requirement though, my other android TV stick is 4.2 and also works perfectly. Its a mk808B.
