Pros: Price, ease of install, plug and play with os x 8.5

Cons: I have not run across any yet. I am thinking of taking one of my Mac Pro's to Maverick. I will order another card, only 4 port for that one. I will post results.

Overall Review: I have 4 Mac Pro's 4.1, also everyone of Mac's notebooks. USB 3.0 has always been a problem for Mac Pro. This is what senior tech support told me. They say you must run latest OS x, haven't talked to them about Maverick. Bottom line, product works as stated. The company is from China, but they strive to give me the best support possible. I appreciate that.
