Tried together with Freaduino Pro 328 (SKU: 173878) and it worked flawlessly. The drivers installed automatically both on 32 and 64 bit Windows 7. As seen in the picture, it has a transparent plastic wrap protection. The pin markings are on both sides and visible after the connectors are inserted.
There is this statement in the product overview: "Data port supports the switch between 5V and 3.3V electrical level (default 5V)". I don't figure out how can I switch to 3.3V levels. I measured the voltage on the TX line and it is at 5V level. As the onboard chip supports 3.3V levels, I think this is easily hackable.
If you want to use it at 3.3V levels, buy something else or hack it (I didn't hacked mine because I had to remove the plastic protection.
Buy this if you want a FTDI converter to upload sketches to usb-less 5V Arduinos or if you need a USB to 5V TTL serial converter.
