Rating : - Not all created the same
One of the sellers of this item is shipping a slightly different card. The seller says that this card is "AKA MOTOROLA LPC810." But, beware-----this card (the Motorola version) is NOT the same as the Startech product. It does not work in Macs!!!! The seller was quick to refund my total purchase amount, and that was nice, but he was really reacting to a low rating that I gave him. I maintain that this was misrepresenting the product because Amazon Customer Reviews clearly say that this card works with a variety of Macs and the one he sent doesn't. Don't make the same mistake if you have a Mac!! Frustrating, and of course it took a week to find all this out.
