Pros: Adds 4 USB 3.0 Super Speed Ports to my PC that only had USB 2.0. Fit well. Installed easily.

Cons: Installation instructions are a bit brief, but accurate and usable. Instructions should specify that one must have a USB 3.0 device and a USB 3.0 cable in order to use SuperSpeed. Otherwise, the port will default back to USB 2.0 transfer speed, as required by the USB 3.0 spec.

Overall Review: After a disastrous attempt to install an NEC/Renesas card and drivers, I ordered this card. This card installs easily, and the supplied drivers installed perfectly on the first attempt. The supplied CD has drivers for a lot of very different cards. The instructions specify exactly which driver to install, so pay attention! The drivers worked for my Lenovo i5 tower with Win 8 64- bit. While the machine will read from my Seagate backup+ at about 27 MB/sec using a USB 2.0 cable, it will transfer at 50-90 MB/sec using a USB 3.0 cable into this new card. This demonstrates that the card is backward compatible to USB 2.0 devices, and how much speed enhancement is available via USB 3.0. Note that a USB 3.0 cable is required to utilize the USB 3.0 SuperSpeed mode, since these cables provide 5 extra conductors to enable the higher speed.

Pros: I replaced the 6GB of memory in an old Windows (8) 10 Lenovo i3. Cards fit perfectly in the slots. Upon startup, the machine accepted the memory upgrade with no objection. Win 10 recognized the 8 GB with no fuss.

Cons: none

Overall Review: The cards worked as intended, so I would buy again if needed, and do recommend to others. This is old, old style memory, not available at my local stores, so I was glad to have it available here.

Pros: I replaced the original 1 GB cards that came in my 2007 eMachine with these 2 GB cards. They fit perfectly, and worked OK, passing the memory check. Windows 7 recognized the new memory with no fuss. Then, I replaced Windows 7 with Linux Mint Cinnamon, which also recognized the new memory with no fuss.

Cons: none.

Overall Review: I would buy this pkg again, and recommend it to others. This is an old old memory style, that's hard to find elsewhere, so I was glad to find it available here.

Product arrived on time, suitably packaged, and undamaged. Popped the memory cards in, and they were immediately recognized by the PC.
