How does the B.Mini differ from the MX-Mini? The functionality looks the same? I know I've seen Mx-Mini's with SMD LEDs before, and apart from that it seems the same.
USB port different position, Bmini is on the left hand side while mx mini is at the middle.
Bmini support:
ISO Enter + 1.25 left shift.
2.75 shift, Backspace 1x 1x .
And last but not least, the RGB smd LEDs.
