Very happy with this product. Aesthetic, efficient (do not connect 4 above 3GB disk at full speed! ...) convenient to connect USB drives, GPS, digital camera or other external HDD 2.5 ". Problem of too rigid cable bothers to fit in a briefcase or even a good position on the work table (should inspire a Macbook Pro power supply cable, flexible and easy to bend) .. . where a star less. But I still redeem if necessary. So satisfied.
