Pros: None.

Cons: This item once plugged into my labtop fried my Samsung 830 256gb drive. I had a really bad smell coming from it. At first it was just connecting and disconnecting. The drive would be recognized then not recognized and keep doing this cycle. I tried playing with it by jiggling the cable and SSD and then it fried. Not worth the paper it was shipped in. bought a Samsung 840 EVO 500gb from Newegg today because of it. Not a happy customer.
