The product works perfectly and is hardly bigger than a 2.5-inch external drive. Of course, it naturally has the defects of his qualities: -The product is small, the introduction of the disc in the box should be done with caution and output too. -The product is metal it's solid, but necessarily heavier than if it was plastic and if you want find fault, one might wish that the hood has a simple locking system (light kind outgrowth under the hood now locked closing, but does not prevent the reopening) The product is therefore entirely consistent with what can be expected and this for a very attractive price! I highly recommend while advising to take his mount nimble fingers disassembly you
