this is the first time I have problems with a product but I'm sorry but I put three stars because I think it is a good product, but I went on a trick that apparently does not work! already the adapter package had no scotch and you could see that the cover was already open! the cd rom was also turned upside down in his pocket and the ledge was open already! I think it has already been sent back once! and we tried it on two computers with two different windows including a windows8 and the other windows7 and ordis whose age does not exceed the past three years! we tried everything and nothing to do, the hard drive spinning thanks to current, but after next usb, total inertia of the two computers that have not seen meme come home! no sound, no tooltip or anything! as if nothing happened! from there, we put the driver in the windows7 and it slammed the wifi driver in passing and without further because it was not installed! it was total horror! suddenly, I sent this morning to refund! unfortunate episode and no luck! we found another solution with a friend to transfer data because it was another case that walked him !! sorry again !!
