Thoughts on the X6S RockChip device?

This device must be a recent release; I can't find any discussion about it anywhere.

X6S Android 4.2 Smart TV Box (Wifi,Blue-tooth,LAN,OTG,USB,HDMI,TF,AV) - USD $ 75.99

I'm interested in using it as a headless wifi repeater and dash cam.

I like it for the form factor, and the fact that it seems to have two removable antennas. (I'll likely run a higher gain/amplified antenna to one of the ports)

Has anybody used one of these before?

Thanks.
