External enclosure for 2.5 "hard drive USB 3.0 perfectly fulfilling its role. I already had the brand USB 2.0. I appreciate the quality brushed metal finish and construction of the product, the ease of assembly (there are only 2 screws to place), very good heat resistance (high passive ventilation) and to have made a real leather and high quality pouch. Noted that this case is thicker than the USB 2.0 model. USB 3.0 interface without reproach, does what must be done, no problem with my PC under Windows 7 64bit.
