The case is plastic rather light and does not seem a bomb proof. The instructions attached is in English, but its size is very small, you'll need a magnifying glass! (I remove a star for that). An HD 2.5 "SATA immediately recognized but not my SSD: I must hand it to control ... Problem solved, the SSD was not initialized or formatted. This box is very convenient to use because it allows to change the hard drive or SSD (in housing) in seconds. The after sales service is at the top, and you can count on him to help you solve a problem with this product!
