Review on Unitek USB 3.0 Compact Flash Card Reader - 3-Slot Multi-Card Adapter for CF, TF, SDXC, SDHC, SD, Micro SDXC, Micro SDHC - Read 3 Cards Simultaneously - Aluminum - 4FT Cable (Black) by Dale Hing

The product seems solid as it has an aluminum body and inserting a CF card is very easy, but when connected to my computer it kinda feels like the other 2 drives on, SD and Micro SD is active and I get warnings that there is no media on those drives when I plug them in. I bought it to be able to take my CF card out of my Nikon D700 and read pictures while I put a new CF card in the camera. While I easily dismiss warnings, this can be a pain. I've also noticed that if for some reason the drive is hit a little it will come loose. The CF card is still plugged in and plugged into the USB port, but the drive no longer lights up and you have to reinsert it into the USB port for it to become active again. They also claim it's USB 3.0, but the transfer speed is more like USB 2.0 when copying files as small as 3 or 4MB, so I only have to give it 3 stars for that reason.
