Summary: I bought this to use with me legacy Acer laptop that has the old standard PCMIA Slots that I wasn't using and a few usb2 ports. The goal was to increase data transfer with this card relative to usb2. It works great, adding two higher-speed USB ports. Be sure to check your PCMIA slot.
Summary: This came with everything needed, driver cd and instructions and power cable. An awful lot of trouble to set up quickly, it gets in the way if you leave it installed. But it works to give my non USB 3.0 laptop a boost. And no Ubuntu 12.04 support for my dual boot setup.
Summary: Pros: If you need USB 3.0 speed on an aging laptop - this is way to go. Worked as soon as I had it plugged in. Cons: Its a bit cumbersome as it occupies a regular USB to power it and on my Lenovo Ideapad it blocked 2 other USB ports - as a result I lost 3 USB 2.0 ports to gain 2 faster ones.
Summary: I would not have bought it had I known it requires a power cable to run from the device to another USB port! On my laptop (VAIO VGN-FW280J) the nearest port is on the OTHER side of the latop. It works fine but now it is yet another cable to deal with.
Summary: This item was bought to replace a faulty USB 3 plug on a laptop utilized in a extensive auto cad program for fabricating items for other companies. It performed very well once set up. However, acquiring the drivers for this item was quite difficult.
Summary: This is the best and affordable alternative I found for making your motherboard USB 3.0 compatible. You can't really get the best out of USB 3 flash drives if your computer's USB port is USB 2.0. This little attachment can make USB 2.0 port into USB 3.0. I would 100% recommended this to anyone.
Won't stay connected long enough for file transfer.

Summary: Won't stay connected long enough for file transfer, moves around too easily in express slot. Requires an extra usb power cord creating another opportunity for causing the card to disconnect in the middle of a file transfer. Virtually unusable.
Took a few reboots, but eventually everything is working

Summary: I installed this on my Lenovo T410 running Windows 7. Immediately after installing (and possibly after one reboot) it will recharge my cellphone, but it did not work as a USB 3.0 port. I tried a few things, including uninstalling and reinstalling the drivers without success.
