What Macbook have you tried QuickerTek QCard2 with?

I wonder which versions of Macbook Air/Pro is QuickerTek QCard2 (2-port) compatible with?

Anyone tried? With which Macbook? Did it work flawlessly? Any compatibility problems?


Buyer beware since this is a total ripoff. I bought one of these overpriced MacBook Pro QCard2 – 3 Port for $149, which turned out to be a used late 2013 13″ MacBook Pro Retina airport/bluetooth card. iFixIt has these for $79.95, so I got ripped off by these bozos.
