Nice add on for older laptop,
Verified Purchase(What is this?)
This review is from: Neewer Expresscard Express 34mm To 2 Port USB 3.0 BC628 5Gbps for PC Laptop
As other reviewers mentioned the product is actually a Gymle branded adapter. I'm running windows 8 and the card will operate as USB2 from the default windows driver, with my usb3 hdd giving 20mb/s read speed. Following other reviewers instructions and installing the drivers the speed increased to 55 -60 mb/s. Great buy for the money.
