    Not Operational

    Cons: Wish it worked out of the box.

    I must have received a dud. After installing the software and plugging in the adapter, the adapter did not light up, make noise, or become accessible to my laptop. I had high hopes for this rather large thumb drive adapter but was sadly unable to use it.

    Worked great for the first 4 months

    Worked great for the first 4 months - now it intermittently loses connection completely - and I have to either press the reset(?) button or unplug/plug back in for it to work... then functions normally until the next time it cuts out again.

    When it works its fantastic.
